A Supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 97 m above the glacier at a speed of 133 m/s.

Before considering the air resistance, the time and range of the object after it hits the ground from a canon is 1.29 s and 17.57 m and the highest height it made was 2.05m. After considering the air resistance, its new time and range is 1.26 s and 16.03 m, respectively and its new height is 1.95 m. What are the effects of air resistance on the range and final height of a projectile? Given that the initial speed, initial height and initial angle were all constant.

A diver steps off the cliffs at Acapulco, Mexico, 27.6 m above the surface of the water. At that moment, he activates his rocket-powered backpack horizontally, which gives him a constant horizontal acceleration of 5.7 m/s2 but does not effect his vertical motion. (For the following questions, ignore any effects of air resistance.) 1) (a) How long does he take to reach the surface of the water? (b) How far out from the base of the cliff does he enter the water, assuming the cliff is vertical? (c) Show that his fight path is a straight line. (Do this on paper. Your instructor may ask you to turn in your work.
