A415-kg container of food and water is dropped from an airplane at an altitude of 300m. first, consider the situation ignoring air resistance. then calculate the more realistic situation involving a drag force provided by a parachute.

1. if you ignore air resistance, how long will it take the container to fall 300m to the ground?

2. again, ignoring air resistance, what is the speed of the container just before it hits the ground?

3. the container is attached to a parachute designed to produce a drag force that allows the container to reach a constant downward velocity of 6m/s. what is the magnitude of the drag force when the container is falling at a constant 6m/s down?
