A steel ball travelling at 8m/s collides with a cart initially at rest. The cart travels to the right at 2.6 m/s after collison. Find the ball’s velocity after the collision.

What was the change in the ball’s momentum?? If the collision lasted 0.001 sec? What was the average force??

What was the total kinetic energy after and before??

mc=0.45kg
vm=0
mb=0.09kg
vm=8m/s

    A ball of mass 0.265 kg that is moving with a speed of 5.1 m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.3 m/s . a) Calculate the velocity of the target ball after the collision. b) Calculate the mass of the target ball. Solve using conservation of momentum and conservation of energy.

    A 1-kg pellet travels with velocity 160 m/s to the right when it collides with a 39-kg hanging mass which is initially at rest. After the collision, the pellet remains lodged in the hanging mass, i.e., it is a completely inelastic collision. The hanging mass (+pellet) then swings upward and reaches a maximum height hmax before swinging downward again. Assume that no external forces are present and therefore the momentum of the system is conserved. What is the velocity vf...

    A 1.0-kg standard cart collides on a low-friction track with cart A. The standard cart has an initial x component of velocity of +0.40 m/s, and cart A is initially at rest. After the collision the x component of velocity of the standard cart is +0.20 m/s and the x component of velocity of cart A is +0.65 m/s . After the collision, cart A continues to the end of the track and rebounds with its speed unchanged. Before the...
