A parachutist's speed during a free fall reaches
180
kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during
20
seconds of free fall? Do not round your answers.

Respuesta :

180 km per hour = = 180,000 m / hr

= 180,000 / 3600 = 50 m/s

For 20 seconds of free fall distance travelled = 20*50 = 1,000 m.
