A parachutist relies on air resistance (mainly on her parachute) to decrease her downward velocity. She and her parachute have a mass of 58.0 kg and air resistance exerts a total upward force of 670 N on her and her parachute. What is the combined weight of the parachutist and parachute? Calculate the net force on the parachutist. What is the magnitude of the acceleration of the parachutist?

Answer:

1. F = 569 N

2. F_net = 101N

3. a = 1.74m/s²

Explanation:

Weight is a force measurement.

F = m*a

F = 58.0kg*9.81m/s²

F = 568.98 N

F_net = 670N+(-569N)

F_net = 101N

a = F/m

a = 101N/58.0kg

a = 1.74m/s²
