When a skydiver reaches terminal velocity, the force of air resistance (also known as drag) acting on the skydiver is equal in magnitude but opposite in direction to the force of gravity acting on the skydiver.
The force of gravity acting on the skydiver can be calculated using the equation:
Force of gravity = mass * acceleration due to gravity
In this case, the mass of the skydiver is given as 50 kg, and the acceleration due to gravity is approximately 9.8 m/s².
Force of gravity = 50 kg * 9.8 m/s² Force of gravity = 490 N
Since the skydiver has reached terminal velocity, the force of air resistance is equal in magnitude but opposite in direction to the force of gravity. Therefore, the force of air resistance is also 490 N.
