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?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
