Intro to Momentum Video Lessons

Concept

# Problem: A rubber ball and a lump of clay have equal mass. They are thrown with equal speed against a wall. The rubber ball bounces back with nearly the same speed with which it hit. The clay sticks to the wall. Which one of these objects experiences the greater momentum change? A. the clay B. the rubber ball C. Both experience the same non-zero momentum change. D. Both experience zero momentum change.

Momentum:

p = mv

We have:

mb = mc = m

v0b = voc = v

For the rubber ball:

|vb0| = |vbf|
