Speed and Motion

1. . Suppose a stretch of land in the savanna is 124 m long. If a cheetah reaches its top speed (starting at rest) within that entire stretch, what is its final speed? Assume acceleration is constant at 4 m/s2 and the cheetah is running in a straight line (towards some unsuspecting prey?). (10 points)

2. You launch a cannonball at an angle of 35° and an initial velocity of 36 m/s (assume yi = yf = 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)
