A ball with mass 0.6 kg is thrown upward with initial velocity 20 from the roof of a building 20 m high. Assume there is a force di air resistance of magnitude directed opposite to the velocit 1325 where the velocity v is measured in m/s. NOTE: Use g=9.8 m/s² as the acceleration due to gravity. Round your answers to 2 decimal places.
