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, \(h_1 = 4.00 m\) Acceleration due to gravity, \(g = 9.8 m/s^2\) Using the equation \(v_1 = \sqrt{2gh_1}\), we can calculate: \(v_1 = \sqrt{2 \times 9.8 \times 4.00} = \sqrt{78.4} \approx 8.85 m/s\) ** Show more…

A ball of moist clay falls $15.0 \mathrm{~m}$ to the ground. It is in contact with the ground for $20.0 \mathrm{~ms}$ before stopping. (a) What is the magnitude of the average acceleration of the ball during the time it is in contact with the ground? (Treat the ball as a particle.) (b) Is the average acceleration up or down?
