PhysCasts: A Ball Bouncing Back: A Vector Calculation in 1-D

Rowlands, W. (Wayne)


In this problem we will be looking at the difference between doing a vector calculation and a scalar calculation. A ball moving horizontally at 20 m/s bounces off a wall, and then moves at 10 m/s in the opposite direction. What is the ball's change in velocity and change in speed?
