Question

A parachutist's rate during a free fall reaches
198
kilometers per hour. What is this rate in meters per second? At this rate, how many meters will the parachutist fall during
10
seconds of free fall? Do not round your answers.

Answer 1

55 meters per second.
Use 1 kmph=0.27 mps
Distance traveled in 10 seconds = 55 x 10 = 550 meters

Answer 2

\[198\,[\text{km/hr}]\\
=198\,[\text{km/hr}]\times1\times 1\\
=198\,[\text{km/hr}]\times\frac{[\text{hr}]}{3600\,[\text s]}\times\frac{1000\,[\text m]}{[\text{km}]}\\
=\]

Answer 3

\[=\left(198\times\frac1{3600}\times 1000\right)\,[\text{m/s}]\\
=\]

Answer 4

for the second part of the question,
use \[v = d/t\]
(solve for \(d\))
