A parachuter, falling with a constant speed, drops 456m in 14.4s. Determine all unknowns.
S =
51
m/s
d =
456
m
t =
14.4
S

The parachuter is falling at a speed of 31.667 meters per second.

Explanation:

Given that parachuter falls at constant speed and travelled distance and time are known, the unknown is speed, measured in meters per second, which is obtained by the following kinematic expression:

Where:

- Travelled distance, measured in meters.

- Time, measured in seconds.

If and , the speed of the parachuter is:

The parachuter is falling at a speed of 31.667 meters per second.
