Abaseball approaches home plate at a speed of 40.0 m/s, moving horizontally just before being hit by a bat. the batter hits a pop-up such that after hitting the bat, the baseball is moving at 56.0 m/s straight up. the ball has a mass of 145 g and is in contact with the bat for 1.90 ms. what is the average vector force the ball exerts on the bat during their interaction? (let the +x-direction be in the initial direction of motion, and the +y-direction be up.)

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great. d) about 10 times as great.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
