Chapter 9.2, Problem 2P

To determine

To Find:The time taken by the T-shirt.

Answer to Problem 2P

The required time is $0.54\text{s}$ and the range of height over this time is $0\text{to}\text{35}\text{ft}$ .

Explanation of Solution

Given:

The velocity is $64\text{ft/s}$ .

The height is $35\text{ft}$

Formula Used:

  $\text{Time}=\frac{\text{Distance}}{\text{velocity}}$

Calculation:

It is given that the upward velocity is $64\text{ft/s}$ and height is $35\text{ft}$ .

Now, find time. Use the formula $\text{Time}=\frac{\text{Distance}}{\text{velocity}}$

  $\begin{array}{c}\text{Time}=\frac{35}{64}\\ =0.54\text{s}\end{array}$

Thus, the time is $0.54\text{s}$ .

The maximum height above court level will be $35\text{ft}$ and minimum will be zero.

Hence, the required time is $0.54\text{s}$ and the range of height over this time is $0\text{to}\text{35}\text{ft}$ .
