Relative Velocity and Projectile Motion . a)An airplane moves horizontally with a constant velocity VA/G 300m/s with respect to ground at height H = 600m. The plane fires a container, which has a speed VC/A = 300m/s and direction α = 300 with respect to the airplane immediately after the firing. The container performs a projectile motion and hits the ground at a horizontal distance L from the point of the firing (see figure a)What is the velocity (horizontal and...

A pool ball moves with a velocity of 5m/s, it hits another ball (with the same mass) which is in repose. After collision, the first ball moves with a velocity of 4.33m/s and an angle of 30° (in respect to the original line of movement). Assuming it's an elastic collision, find the velocity and angle of the second ball. Answer: Vf=2.5m/s at 300°

One kind of elevator has the elevator car hanging from a cable,
which then passes over a pulley and connects to a counterweight, as
shown in (Figure 1). The mass of a fully-loaded elevator (that is,
the elevator and all its passengers) is 1850 kg , the mass of the
counterweight is 1500 kg , and the pulley has a radius of 0.4 m
and a mass of 400 kg . A motor drives the motion of the elevator by...
