1. The problem statement, all variables and given/known data A 0.624kg basketball is thrown straight down and strikes the floor at a speed of 7.10m/s. The floor applies an average force of 67.2N for a duration 0.120s, causing the ball to bounce back upward. How high does it bounce? 3. The attempt at a solution I'm not actually sure on the equations needed to figure out this problem, I guess that is why I'm having a hard time with it. I know were dealing with projectile motion but I also know it has to deal with peak height which is : y = viy • t + 0.5 • g • t2 I think it's the bounce of the object and 0.120s of 67.2N force that has me thrown off.
