A ball with mass m kg is thrown upward with initial velocity 23 m/s from the roof of a building 17 m high. Neglect air resistance. Use g = 9.8 m/s?. Round your answers to one decimal place. (a) Find the maximum height above the ground that the ball reaches. Xmax = meters (b) Assuming that the ball misses the building on the way down, find the time that it hits the ground. lend = i
