2. You launch a cannonball at an angle of 45° and an initial velocity of 40 m/s (assume yi = yp = 0 meters). Calculate the time the cannonball spent in the air. Assume no air resistance and that the cannonball is launched on Earth (g = -9.81 m/s2). (10 points)
1. Cheetahs can reach a top speed of 34 m/s (about 76 mph). Suppose a stretch of land in the savanna is 130 m long. If a cheetah reaches its top speed (starting at rest) within that entire stretch, what is the rate of acceleration? Assume acceleration is constant and the cheetah is running in a straight line (towards some unsuspecting prey?). (10 points)
