Chapter 3.3, Problem 46PP

(a)

To determine

The shape of the velocity-time graph after first two bounces.

Answer to Problem 46PP

The shape of the velocity-time graph looks like the teeth of the seesaw.

Explanation of Solution

Given Info:

The initial height of the basketball is, $h_1=1.5\text{m}$ .

The height of the basketball after first bounce is, $h_2=0.75\text{m}$

The height of the basketball after second bounce is, $h_3=0.25\text{m}$

Calculation:

The graph of the velocity-time graph of the basket ball is given in figure (1).

Figure (1)

The shape of the velocity-time graph looks like the teeth of the seesaw.

(b)

To determine

The shape of the position-time graph after first two bounces.

Answer to Problem 46PP

The shape of the position-time graph looks like the steps.

Explanation of Solution

Calculation:

The graph of the velocity-time graph of the basket ball is given in figure (2).
