The position-versus-time graph below shows Object A (solid line) and Object B (dashed line) moving along the same axis and colliding. Do they undergo a totally inelastic collision? Remember, the objects in a totally inelastic collision must stick together, and the momentum of the system must be the same before and after the collision. Check ONE answer.
Yes
No
The velocity-versus-time graph below shows another collision between Object A (solid line) and Object B (dashed line).
Does the graph represent a totally inelastic collision?
A cannon sits at rest on a horizontal and frictionless surface. A cannonball is fired horizontally from the cannon. The speed of the cannonball will be the same as the speed of the recoiling cannon:
because momentum is conserved.
because velocity is conserved
because both velocity and momentum are conserved.
if the mass of the cannonball equals the mass of the cannon. correct
A 0.5 kg piece of clay moving at 2 m/s collides and sticks to a 5.5 kg bowling ball that is initially at rest. After the clay sticks to the ball, what is the momentum of the system? Assume a closed system of the ball plus the clay.
0.09 kg.m.s^-1
1 kg.m.s^-1
11 kg.m.s^-1
12 kg.m.s^-1
Two identical carts are traveling toward each other at the same speed. The carts collide, stick together, and stop immediately after the collision. Which of the following is a true statement about the final momentum of the system?
The final momentum is zero because the momentum dissipated as heat during the collision.
The final momentum is zero because prior to the collision each cart had the same magnitude, but opposite directions of momentum.
The final momentum is zero because the forces acting on the carts cancelled each other out.
The final momentum is zero because momentum disappears during an inelastic collision.
