Question

a parachutists rate during a free - fall reaches 108 miles per hour. what is this rate in feet per second? at this rate, how many feet will the parachutist fall during 5 seconds of free - fall? in your computations, use the fact that 1 mile is equal to 5280 feet. do not round your answers. rate: ft/s distance fallen in 5 seconds: ft

Explanation:

Step1: Convert miles per hour to feet per hour

$108\times5280 = 569040$ feet per hour

Step2: Convert feet per hour to feet per second

$\frac{569040}{3600}=158.066\cdots$ feet per second

Step3: Calculate distance in 5 seconds

$158.066\cdots\times5 = 790.333\cdots$ feet

Answer:

Rate: $158.066\cdots$ $\frac{ft}{s}$
Distance fallen in 5 seconds: $790.333\cdots$ ft
