A 0.1-kg steel ball is dropped straight down onto a hard horizontal floor and bounces straight up. Its speed just before "and just after " with the floor is 10m/s.

Determine the magnitude of impulse delivered to the floor by the steel ball.

Question #3
A 0.50kg-bomb is sliding along an icy pond (frictionless surface) with a velocity of 2.0 m/s to the west. The bomb explodes into two pieces. After the explosion, a 0.20-kg piece moves south at 4 m/s.

What are the components of the velocity of the 0.30-kg piece?

Question #4
Two cars of equal mass collide on a horizontal frictionless surface. Before the collision, Car A is at rest while Car B has a constant velocity of 12m/s. After the collision, the two bodies are stuck together

What is the speed of the composite body (A+B) after the collision?

Question #5

The head of a hammer (m=1.5kg) moving at 4.5 m/s strikes a nail and bounces back with the same speed after an elastic collision lasting 0.075 s.

What is the magnitude of the average force the hammer exerts on the nail?
