A donut drops to the floor. The donut’s mass is 0.90 kg and
it falls from a height of 1.4 m. After hitting the ground, the
donut bounces up and reaches a height of 1.0 m above the floor.
What is the impulse of the floor on the donut?
Mass (m) = 0.90 kg Initial speed during fall (uf) = 0 Acceleration during fall (af) = 9.8 m/s2 Distance of fall (hf) = 1.4 m Speed of donut just before hitting the ground (vf) can be
