Problem 49P

A 100 g block on a frictionless table is firmly attached to one end of a spring with k = 20 N/m. The other end of the spring is anchored to the wall. A 20 g ball is thrown horizontally toward the block with a speed of 5.0 m/s.

a. If the collision is perfectly elastic, what is the ball’s speed immediately after the collision?

b. What is the maximum compression of the spring?

c. Repeat parts a and b for the case of a perfectly inelastic collision.

Solution

Step 1 of 4

In this problem, we have to find the ball’s speed immediately after the collision, then the maximum compression of the spring and also inelastic collision for both part A and B.
