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?

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.
