Best ResponseYou've already chosen the best response.0Accelerationtime graph dw:1342512372407:dw Velocity time graph dw:1342512427429:dw Now about the position time graph

Best ResponseYou've already chosen the best response.0dw:1342512503350:dw which curves(of the 3) will be steeper?

Best ResponseYou've already chosen the best response.0ace increases from origin to t1 constant from t1 to t2 and decreases from t2 onward. but ace is max from t1 to t2. I hope im understandable

Best ResponseYou've already chosen the best response.1ok, so u want to know how will the positiontime graph look like?

Best ResponseYou've already chosen the best response.1I'm not sure, but maybe it looks like this: dw:1342513483775:dw correct me if i'm wrong.

Best ResponseYou've already chosen the best response.0dw:1342513648649:dw ace remains positive always

Best ResponseYou've already chosen the best response.1yea, i was going to type in that right now. the max point should not be reached. since V is not 0 anywhere.

Vaidehi09

Best ResponseYou've already chosen the best response.1the graph should be steeper from origin to t1 than in the interval t1  t2.

Best ResponseYou've already chosen the best response.1@Ishaan94 the velocity is NOT constant from t1 to t2. accel is.

Best ResponseYou've already chosen the best response.0velocity is NEVER constant

Best ResponseYou've already chosen the best response.0dw:1342513895634:dw The graph should look somewhat like this I want to know the order of their steepness.

Vaidehi09

Best ResponseYou've already chosen the best response.1i think the graph should be of this form: dw:1342513986456:dw

Best ResponseYou've already chosen the best response.11 will be more steep than 2.

Best ResponseYou've already chosen the best response.0the ace is always positive so the velocity always increases and so the slope of xt graph always increases

Best ResponseYou've already chosen the best response.1sry my bad! i saw the slop of accel!

Best ResponseYou've already chosen the best response.0ace decreases t2 onward but stays positive notice

Vaidehi09

Best ResponseYou've already chosen the best response.1i think the order of steepness should be 1 > 2 > 3. i'm just using logic here: accel is increasing from 0 to t1 hence vel is increasing at the fastest rate in this interval. from t1 to t2, accel is constant. so vel is increasing at a constant rate ( this rate < the rate from 0 to t1). and from t2 to the end, accel is decreasing. so the vel is anyway decreasing. so less distance will be covered as compared to the former 2 intervals.

Best ResponseYou've already chosen the best response.0the rate of increase of velocity is max from t1 to t2 because ace is max(constant)

shayanreloaded

Best ResponseYou've already chosen the best response.0and from t2 the velocity increases but at a decreasing rate

Best ResponseYou've already chosen the best response.0@Ishaan94 you lost me

Best ResponseYou've already chosen the best response.0even after t2 ace is positive so slope cant be curving down right?

Vaidehi09
 3 years ago
Best ResponseYou've already chosen the best response.1i think it should be curving down. because now the distance covered per unit time is decreasing. so 3 should be the least steep of all.

shayanreloaded

Best ResponseYou've already chosen the best response.0but if ace is positive xt curve never curves down

Vaidehi09

Best ResponseYou've already chosen the best response.1right now, the interval we're considering is this: dw:1342514762867:dw so at some point the graph will curve downwards, but we don't have that within our interval.

Best ResponseYou've already chosen the best response.0but that works only for constant ace part what about the rest?

shayanreloaded

Best ResponseYou've already chosen the best response.0and i just want the order @Ishaan94

Vaidehi09

Best ResponseYou've already chosen the best response.1@Ishaan94 yea, i think we can leave the precision out for this sum. just an approximation ill suffice.

Vaidehi09

Best ResponseYou've already chosen the best response.1okay, here's my final guess: 2 > 1 > 3.

Vaidehi09
 3 years ago
Best ResponseYou've already chosen the best response.1or should it be 2 > 1 = 3 ?

shayanreloaded

Best ResponseYou've already chosen the best response.0Lets keep the question open for more opinions

Vaidehi09

Best ResponseYou've already chosen the best response.1tell me this: accel is increasing and decreasing at the same rate from 0 to t1 and from t2 to the end. so what happens to the distance covered per unit time during these intervals? will the be equal?

Ishaan94

Best ResponseYou've already chosen the best response.1I am sorry for deleting my previous posts. Acceleration is positive from t2 and on wards but I presumed it to be negative :( My latest attempt. I know it sucks but still

Ishaan94

Best ResponseYou've already chosen the best response.1Oops wrong curve, from t1 to t2, it should be dw:1342517034897:dwA parabola.

Vaidehi09

Best ResponseYou've already chosen the best response.1so the answer is 2 > 1 > 3 right?

Ishaan94

Best ResponseYou've already chosen the best response.1I am sorry. I can't be sure from what it seems my graph from t2 can't be right. VelocityTime graph form t2 is downward parabola right? a = dv/dt?

Best ResponseYou've already chosen the best response.1Darwin... this is so embarrassing :(

Vaidehi09

Best ResponseYou've already chosen the best response.1it tends to go downwards. but doesn't do so completely.

Ishaan94

Best ResponseYou've already chosen the best response.1so my graph from t2 isn't right either

Ishaan94

Best ResponseYou've already chosen the best response.1i hope my math is right

Best ResponseYou've already chosen the best response.1mukushla just to be sure of my answer. can you draw an approximate graph? please.

Best ResponseYou've already chosen the best response.3Velocitytime is: dw:1342520614050:dw with 2 halfparabolas between 0 and t1 and between 0 t2 and tfinal

VincentLyon.Fr

Best ResponseYou've already chosen the best response.3Displacementtime is: dw:1342520737774:dw The curve is always increasing as well as increasing in slope. Only the curvature becomes 0 at the end (would go on in a straight line if acceleration remains 0 or would reach an inflexion point if acceleration becomes negative after tfinal

Ishaan94

Best ResponseYou've already chosen the best response.1Seems like I made a fool of myself. But Vincent, slope isn't always increasing. It's constant from \(t_1\) to \(t_2\).

Ishaan94

Best ResponseYou've already chosen the best response.1And it's decreasing from \(t_2\). Correct me if I am wrong. :

Best ResponseYou've already chosen the best response.3@Ishaan what you say is true of velocity, but wrong about displacement

Best ResponseYou've already chosen the best response.0so whats the order of steepness?? 3>2>1 ? or 1=2<3 ? does it depend on ace magnitude or rate of change of ace??

shayanreloaded

Best ResponseYou've already chosen the best response.0@VincentLyon.Fr

VincentLyon.Fr
 3 years ago
Best ResponseYou've already chosen the best response.3The steepness (of displacement curve) is ever increasing because velocity is; so 3>2>1 But, as velocity is a continuous function, the 3 parts of the curve will smoothly link together, without any angle at t1 and t2
