Question

A parachutist's rate during a free fall reaches 189 kilometers per hour. What is this rate in meters per second? At this rate, how many meters will the parachutist fall during 5 seconds of free fall? Do not round your answers.

Answer 1

• 52.5 m/s
• 262.5 m

Explanation:

a) 189 km/h = (189 km/h)(1 h/(3600 s))(1000 m/km) = 189/3.6 m/s = 52.5 m/s

__

b) In 5 seconds, the parachutist will fall ...

(5 s)(52.5 m/s) = 262.5 m
