Is it meters per second or miles per second?
meters per second
I know you may not like this, but I'm going to say that the bullet never touches the aircraft. I may off on something, but I think I'm right.
is ur conclusion based on any solution or....?
I think I see where I'm wrong. It has to do with the bullet velocity. I'll redo.
I need to know what this muzzle velocity of the projectile is 735 mps is?
the muzzle velocity is the velocity of the projectile of the bullet as it leaves the muzzle of the gun. it is 735 mps
Is it a horizontal component or vertical component or both or what. It tells me the slope but you can't use it directly because its probably a reduced form the slope. Slope is velocity and they say 4 up and 3 right, but you can't take those values literally. 8/6 is same as 4/3 so we don't know.
Is it 735 in the vertical or horizontal? That's what I need to know.
well, i think it is both the horizontal and vertical v.
and thats the problem.
but i think that we can get the horizontal and vertical v though the slope. use the slope to get the angle, then after u get the angle, use the 735 mps and the angle to get the vx and vy...im not sure with that
i think i got it hang on
I looked at this question earlier. Honestly, it doesn't really make sense. They stipulate the angle and then they ask for the angle. Make sure you got the wording right, or, if there's a diagram that somehow explains this, post it.
well, i agree with u @Algebraic! because u can simply get the angle with the given slope. im also confused with that, but maybe the point is that we will use the angle to get the vx and vy, and then use the equations to get the theta
changing the angle changes Vx and Vy.
yet they stipulate Vy/Vx ... doesn't make sense.
is this from an online problem set? or if it's from a text book, can you scan and post the pic. or take an ss?
it is from a book, but there's no picture. i posted exactly the same problem as it is in the book
Well, I've tried interpreting this problem statement in a way that somehow makes sense.. but nothing has come to me.
or maybe we won't be using the slope....haha, i just don't know
please help =(
this is our homework to be submitted tomorrow....=(
=( i just don't know what to do
and i dont think the speed of the plane matters at all
the angle between the muzzle and horizontal plane is tan-1(4/3)or 53.13 roughly. thus the initial vertical velocity of the missile is 735*Sin(53.13) or 588 m and accn is 9.8 mps^2 towards the ground. thus using the formula s = ut-.5gt^2 the time taken to reach 5390 m comes to be 10 secs. In this 10 secs the projectile moved horizontally 10*735*cos(53.13) metres or 4410 metres. and the plane has moved 2780 metres. Thus the plane was initially at (4410-2780) or 1630 metres horizontal distance from muzzle. thus the initial angle becomes tan-1(5390/1630) m or 73.174 m.
thnx a lot =)))))))))))
How can the angle be arctan(4/3) =53 and then at the end its 73 ???
