Question1
A parachutist relies on air resistance (mainly on her parachute) to reduce her downward velocity. She and her parachute have a mass of 55.0 kg, and at a particular moment air resistance exerts a total upward force of 620 N on her and her parachute.
(a) What is weight of the parachutist?
(b) Illustrate a free-body diagram for the parachutist. Utilize that diagram to compute net force on the parachutist. Is net force upward or downward?
(c) What is the acceleration (magnitude and direction) of parachutist?
Question2
Describe the force vectors acting on m1 such that their tails align with the center of the block labelled m1. Illustrate the force vectors acting on m2 with their tails aligned with the center of the block labelled m2. The orientations of your vectors will be graded but not lengths.
