Chapter 9: Q. 9.172 (page 1106)

A window washer dropped a squeegee from a platform 196 feet above the sidewalk Use the formula $t = \frac{\sqrt{h}}{4}$ to find how many seconds it took for the squeegee to reach the sidewalk.

Short Answer

Expert verified

The required time is $7 s$

Step by step solution

Step 1:Given information

Given the time is given by $t = \sqrt{\frac{h}{4}}$

Substitute h=196 to get the time

Substituting, we get

$t = \sqrt{\frac{h}{4}} t = \sqrt{\frac{196}{4}} t = \frac{14}{2} t = 7 s$

Checking the time

Checking , we get

$7 = \sqrt{\frac{196}{4}} 7 = \sqrt{49} 7 = 7$

So its correct
