Bouncing a ball!
Hey all, Just wondering if anyone could help me with this handful of questions? thank you.
IF you can't specific ways to figure them out, please tell me the logic/theory. thanks :D
Inital velocity = 10m/s, final velocity = 8m/s. mass = 80grams.
6 The time of contact between the ball and the floor during the bounce was 0.0500 s.
A. Calculate the average net force acting on the ball during its contact with the floor.
F = MΔV / ΔT
F = 0.08*10/0.05
F = 16 N
B. Calculate the average force that the floor exerts on the ball.
F = MΔV/ΔT
= 0.08*18/0.05
= 28.8 N
C. Calculate the average force that the ball exerts on the floor.
Fav = P1(mΔv) + P2(mΔv)
= 0.08*10 + 0.08*8
= 1.44 / 2
= 0.72 kg-1 m/s
Basically my question is, what are these forces and how are they calculated? thanks alot!
