Physics Lab Question
In this lab, we select different types of balls (bouncy, tennis, ect.) and drop each from 1m, onto a hard surface, and record how high the first bounce is. Then we have to determine the velocity of the ball before it hit (neglecting air resistance), and after it hit, the total energy the ball had before and after it hit, the momentum it had before and after it hit, and the change in momentum.
Then I am asked to "determine the impulse that acted on the ball" Uhh, how?
Case in point: Bouncy Ball
Mass: .00856 kg
Momentum before collision: -.038 kg/m/s
Momentum after collision: .020 kg/m/s
Change in Momentum: .058 kg/m/s
How do you find the impulse that acted on the ball? If velocities are needed let me know.
