  A person with mass 80 kg stands on a raft with mass 15kg t that is initially rest on a still pond. The person begins to walk the raft with a speed of+0.5 m/s , as shown. What will the resulting velocity of the raft be as the person walks forward?
  A red ball with a mass of 8kg is suspended from a string. It is struck by a 2 kg blue ball moving to the right at 5 m/s, as shown. After the collision, the blue ball comes to a complete stop. What is the maximum height reached by the red ball?
.An object of mass 2 kg has a linear momentum of magnitude 6kg.m/s. What is this object’s kinetic energy?
A ball of mass m traveling horizontally with velocity v strikes a massive vertical wall and rebound back along its original direction with no change in speed. What is the magnitude of the impulse delivered by the wall to the ball?
Two frictionless carts (mass= 500 g each) are sitting at rest on a perfectly level table. The teacher taps the release so that one cart pushes off the other. If one of the carts has a speed of 2 m/s, then what is the final momentum of the system (in kg.m/s)?
Two identical frictionless carts, each with a mass of 500 g, are initially at rest on a horizontal frictionless surface. The carts push off each other due to a release mechanism. If one cart moves to the right with a velocity of 2.0 m/s after the push, what is the velocity of the second cart?
A ball with a momentum of 5.0 kg·m/s hits a wall and bounces straight back without losing any kinetic energy. What is the change in the ball’s momentum?
Two objects, one of mass3kg moving with a speed of 2 m/s and the other of mass 5 kg and speed 2 m/s, move toward each other and collide head on. If the collision is perfectly inelastic, find the speed of the objects after the collision
 Two blocks, with masses and speeds indicated in the figure, move toward each other. There is negligible friction between the blocks and the horizontal surface. The blocks collide and stick together. How much mechanical energy is lost during the collision?
The graph represents the net force exerted on a box as it slides across a tabletop. Which of the following expressions correctly represents the impulse delivered to the box during the time interval shown in the graph?
