Question

To test the quality of a tennis ball, you drop it onto the floor from a height of 4.00 m. It rebounds to a height of 2.00 m. If the ball is in contact with the floor for 12.0 ms,(a) What is the magnitude of its average acceleration during that contact and(b) Is the average acceleration up or down?

Step 1

Given: Initial height (h1) = 4.00 m Acceleration due to gravity (g) = 9.80 m/s^2 Using the formula: u = √(2gh1) u = √(2 * 9.80 * 4.00) u = √78.4 u ≈ 8.85 m/s Show more…
