Q. 345 - Intermediate Algebra

Question

A hang glider dropped his cell phone from a height of 350 feet. Use the formula $t=\frac{\sqrt{h}}{4}$ to find how many seconds it took for the cell phone to reach the ground.

Step-by-Step Solution

Answer

The time took for the cell phone to reach the ground is 4.6 seconds.

Step 1. Given information

A hang glider dropped his cell phone from a height of 350 feet follows the relation $t=\frac{\sqrt{h}}{4}$.

Step 2. Finding time by using the formula

$$\begin{gathered} t=\frac{\sqrt{h}}{4} \\ t=\frac{\sqrt{350}}{4}=\frac{18.7}{4}=4.6 \end{gathered}$$
