Best ResponseYou've already chosen the best response.1i was plannign on using Vf = Vi X a.t but i don't have the initial velo

Best ResponseYou've already chosen the best response.1what do i do with that?!?!?!? what will i get tho?!?!?!?

Best ResponseYou've already chosen the best response.1I think you have calculated the net accn wrong...

Best ResponseYou've already chosen the best response.1can you please take 2 seconds and go back and read 49b)

Best ResponseYou've already chosen the best response.1Ok, let's see that part again. There are 3 forces acting on the elevator. Force due to the elevator cable upwards, force of friction downwards and gravitational force downwards. Right?

Best ResponseYou've already chosen the best response.1are you saying that i should have combined the frictional and gravitational forces?!?!? Applied force  ""(Frictional force + Gravitational Force)"" = Net Force

Best ResponseYou've already chosen the best response.1Yeah, that's what i am saying !!

Best ResponseYou've already chosen the best response.1but i didn't include the gravitational force for some reason idek. i though once an object overcome the force of gravity, the effects of gravity don't count.

Best ResponseYou've already chosen the best response.1ok please help me here for a sec. If an object is travelling faster than 9.80m/sec^2 up, does the effects/ the gravitational force count?

Abhisar

Best ResponseYou've already chosen the best response.1Yes, gravity is always working. Suppose a body is of mass 1 Kg is travelling with an acceleration 10m/s^2 then it means that force acting on it is 20 N. 10 N is used in neutralising the gravitational force and then other 10N for giving its acceleration.

Best ResponseYou've already chosen the best response.1because imagine if your inside an elevator which is going at 15m/sec^2, your initial mass is 50Kg, would you not feel heavier due to the sheer upward force the evelator is pressing you with?????

Best ResponseYou've already chosen the best response.1ok...so once i have my net acceleration how do i determine the velocity of the elevator? Please just leave the formula. and i'll do the rest :)

Best ResponseYou've already chosen the best response.1v=u+at V is your final velocity, u is your initial velocity which is 0 in this case, a and t are acceleration and time.
