2. Problem #37 from Chapter 10 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...

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...

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...

7. A ping pong ball of mass 2.7 g is thrown towards a wall at 20 m/s. The ball's collision with the wall lasted 0.07s before rebounding off of the wall with a velocity of -10m/s. What was the force produced during the collision (in N)?

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:...

Suppose the mass of the ball is 60 g and it is spinning at 40 rad/s at a distance of 1.5 m from the center of rotation. The force is 1800 N and it’s applied for 2 ms. Your goal is to find the final angular speed of the tennis ball. i. What is the initial angular momentum of the tennis ball? Hint: 40 rad/s is the angular speed (?), NOT the linear speed (?). If the angular speed is...
