The net force on the skydiver is 300 N, down.
Explanation:
The formula for calculating net force is F_net = m*a, where F_net is the net force, m is the mass, and a is the acceleration. Substituting the given values, we get:
F_net = 50 kg * (-6 m/s^2) = -300 N
The negative sign indicates that the force is acting downwards, which makes sense since the skydiver is falling downwards. Therefore, the answer is 300 N, down.
The net force acting on the skydiver can be determined using Newton's second law, which states that force (F) equals mass (m) multiplied by acceleration (a). In this case, the mass of the skydiver is 50 kg, and the acceleration is 6 m/s^2 down. Therefore, the net force on the skydiver can be calculated as follows:
F = m * a
F = 50 kg * 6 m/s^2
F = 300 N, down
So, the correct answer is 300 N, down.
