A physics teacher pushes a 80kg environmental science teacher out a helicopter without a parachute from a helicopter 450m above the ground. The environmental science teacher experiences an average drag of 169N for the first 7.0s of the fall, then falls the rest of the way with a constant, terminal speed. Assume the environmental science teacher is initially at rest. What is the teacher's terminal speed? What is the magnitude of the teacher's acceleration during the first part of the fall? unit unit How far does the teacher fall before reaching terminal speed? What is the strength of the drag force while the teacher falls with terminal speed? unit How long does the teacher take to hit the ground (total)? unit unit
