Problem 21PE
A 60-kg and a 90-kg skydiver jump from an airplane at an altitude of 6000 m, 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)? Assume all values are accurate to three significant digits.

Problem 21PE
A 60-kg and a 90-kg skydiver jump from an airplane at an altitude of 6000 m, 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)? Assume all values are accurate to three significant digits.
ANSWER:
Solution 21PE :
Step 1 of 4:-
The masses of two skydivers are,
,
.
The height from which they jumped is, .
Assuming the fact that very quickly they achieved their respective terminal velocities, the time taken by each of them to reach the ground has to be calculated.
