A hollow ping-pong ball is projected upward at ? = 0. The velocity of the ball is given by ?(?) = 40.0 ?/?*?^(−?t) − 3.0 ?/?, where ?= 2.00 1/? is a numerical constant. (a) What is the displacement of the ball between ? = 0 and ? = 1.20?? Give the magnitude and direction. (b)What is the average velocity of the ball between ? = 0 and ? = 1.20?? Hint: Use the result of part (a) to answer part (b).
Please explain the steps.

3. A ping-pong ball is a hollow sphere that has a radius of 0.100 m and a mass of 0.00270 grams. At one point during a game of table tennis the ball is initially rotating at 100 rad/s counterclockwise (around its center of mass) before being hit by a paddle. The hit from the paddle changes the angular velocity to 60 rad/s clockwise in a time of 0.200 seconds. (a) Through how many radians will the ball turn...

1. A ping pong ball (ball #1, mass of 2g) is held just above a tennis ball (ball #2, mass of 57g) with their centers vertically aligned. When the balls are released, they fall through a vertical distance of 1.27 meters. a) Prove that each ball is traveling at 5.00 m/s just before it hits the ground. The tennis ball (#2) hits the ground and bounces elastically off of it before the ping pong ball (#1) actually hits #2. Since...

Relativistic ping-pong In the lectures, we determined the paddle velocity (relative to earth) such that a ball travelling at 10m/s in the earth frame, would leave the paddle at 15 m/s in the earth frame. To solve this problem it was useful to use the paddle-fixed frame. With a heavy (compared to ball) paddle, we could neglect the influence of the ball on the motion of the paddle. Repeat this type of calculation for relativistic speeds using relativistic velocity addition:...
