Clearly state the law of the conservation of momentum.
The total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.

Consider the impulse momentum theorem, and an egg hitting a brick wall. Is the force of impact low and the change in time high? Or is the opposite true?
The opposite is true.

After being struck by a bowling ball, a 1.5 kg bowling pin slides to the right at 3.0 m/s and collides head on with another 1.5 kg bowling pin, initially at rest. What is the velocity of the second pin if the first pin stops moving when it hits the second pin?
3.0 m/s to the right

Compare the change in momentum of two objects which have the same initial velocity of 443 m/s. The first object hits a wall and the time of impact is 0.23 seconds. The second object also hits the same wall, but the impact time is 0.19 seconds.
change in momentum is the SAME

After being struck by a bowling ball, a 1.5 kg bowling pin slides to the right at 3.0 m/s and collides head on with another 1.5 kg bowling pin, initially at rest. What is the velocity of the second pin if the first pin moves to the right at 0.5 m/s after the collision?
2.5 m/s to the right
