A ball with mass 0.85 kg is thrown upward with initial velocity 10 m/s from the roof of a building 20 m high. Assume there is a force due to |v|| air resistance of magnitude directed opposite to the velocity, where 30 the velocity is measured in m/s. NOTE: Use g-9.8 m/s as the acceleration due to gravity. Round your answers to 2 decimal places. a) Find the maximum height above the ground that the ball reaches. Height: 24.85 m X b) Find the time that the ball hits the ground. Time: 3.284 seconds
