Aball with mass of 0.050 kg is dropped from a height of h1 = 1 .5 m. it collides with the floor, then bounces up to a height of h2 = 1.0 m. the collison takes 0.015 s.
use part e to calculate impulse ( j) ? write the formula first .
use part f to calculate the average force acting ( f) on the ball by the floor during the collision?
*write the formula
calculate the change in the kinetic energy (∆k) in the collision. write formula first.
what happens to the lost kinetic energy?
what type of collision is this?
