Answer:
It took the cell phone 4.15 seconds to reach the ground
Step-by-step explanation:
The formula is [tex]t=\frac{\sqrt{h}}{4}[/tex] , where t is the time and h is the height
The height of that the cell phone dropped from it is 275 feet above the ground
∴ h = 275
- Substitute the value of h in the formula to find t
∵ [tex]t=\frac{\sqrt{275}}{4}[/tex]
∴ [tex]t=\frac{5}{4}\sqrt{11}[/tex]
- Change it to decimal
∴ t = 4.15 seconds to the nearest 2 decimal places
It took the cell phone 4.15 seconds to reach the ground
