A parachutist's speed during a free fall reaches 189 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 15 seconds of free fall? Do not round your answers.

Speed of the parachutist = 189 km/h

The speed in m/s .

km/h × 5/18 = m/s

189 km/h × 5/18 = 52.5 m/s

Time Given: 15 seconds

Distance = Speed × Time

Distance = 52.5 × 15 = 787.5 metres

The speed is 52.5 m/s .

The parachutist will fall 787.5 metres during 15 seconds of free fall with that speed.
