Answer:
The speed of the resistive force is 42.426 m/s
Explanation:
Given;
mass of skydiver, m = 75 kg
terminal velocity,
The resistive force on the skydiver is known as drag force.
Drag force is directly proportional to square of terminal velocity.
Where;
k is a constant
When the new drag force is half of the original drag force;
Therefore, the speed of the resistive force is 42.426 m/s
