A 60.0-kg and a 90.0-kg skydiver jump from an airplane at an altitude of , both falling in the pike position. Make some assumption on their frontal areas and calculate their terminal velocities. How long will it take for each skydiver to reach the ground (assuming the time to reach terminal velocity is small)

The terminal velocity for both skydiver are 99.58 m/s and 121.9 m/s.

The time for both skydiver are 60.25 sec and 49.22 sec

Explanation:

Given that,

First mass = 60 kg

Second mass = 90 kg

Suppose, altitude

Area =.14 m²

C= .7

Density = 1.21 kg/m³

We need to calculate the terminal velocity

Using formula of terminal velocity

For first mass,

Put the value into the formula

For second mass,

Put the value into the formula

We need to calculate the time of first skydiver

Using formula of time

Put the value into the formula

We need to calculate the time of second skydiver

Using formula of time

Put the value into the formula

Hence, The terminal velocity for both skydiver are 99.58 m/s and 121.9 m/s.

The time for both skydiver are 60.25 sec and 49.22 sec
