A rocket is fired at 48m/s, in a direction 400 to the horizontal. It explodes in mid air, 4s after the launch. Find the speed of the rocket just before the explosion.(assume that the motion of the rocket is approximately similar to a projectile motion)
This has me stumped!
Homework Answers
u = 48 m/s
ux = 48 cos 40
uy = 48 sin 40
t = 4s
vy = uy + at
= 48 sin 40 - ( 9.8) * 4
= -8.346 m/s
v = sqrt ( vx^2 + vy^2)
= 37.705 m/s

A model rocket has a mishap in air, and it explodes apart into two pieces. The 3.0 kg rocket was traveling at velocity <0, 9, 0> m/s just before the explosion, and the 2.0 kg piece of rocket is traveling at velocity <4, 8, 0> m/s just after the explosion. What is the velocity of the 1.0 kg piece just after the explosion?

At a height h = 44.0 m above the ground a rocket is fired at an initial speed v0 = 168.0 m/s at an angle θ = 27 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component...
