A physics teacher pushes an environmental science teacher out of a stationary helicopter without a parachute from a height of 480m. Approximate the motion by assuming that the environmental science teacher begins at rest and falls freely for the first 3.70s then maintains a constant velocity until hitting the ground.

How far did the environmental science teacher fall-freely?
What was his maximum speed?
What was the total time of his fall?
