A ball is shot from the ground into the air. At a height of 9.1 m, its velocity is = 7.2î + 7.0ĵ m/s, with i horizontal and upward. (a)VTo what maximum height does the ball rise? (b) What total horizontal distance does the ball travel? What are the (c) magnitude and (d)angle (below the horizontal; give as negative) of the ball's velocity just before it hits the ground? A motorcyclist who is moving along an x axis directed toward the east has an acceleration given by a = (6.60 - 1.20t) m/s² for 0 ≤t≤ 6.0s. At t = 0, the velocity and position of the cyclist are 3.10 m/s and 7.3 m. (a) What is the maximum speed achieved by the cyclist? (b)What total distance does the cyclist travel between t = 0 and 6.0 s?

An arrow is shot into the air and reaches its maximum height of 6.00m above the horizontal from which it was shot. On its way back down it lands on a ledge 5.00m above the horizontal from which it was shot and 8.00m horizontally away from the archer. What was the arrow’s initial velocity?
In 2007, Michael Carter (U.S.) set a world record in the shot put with a throw of 24.77 m. What was the initial speed of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0° above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45° when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus, 38° will give a longer range than 45° in the shot put.)
