I need the work for all of the questions thank you !

14. A 0.500 kg rock is shot upwards at a speed of 36.0 m/s. Assume the rock goes straight upwards and there is no energy lost. a) What is the rock's kinetic energy at the moment it is released? b) Assuming all of the rock's kinetic energy is converted into gravitational potential energy, what is the maximum height it will reach? 15. A 0.450 kg baseball comes off a bat and goes straight up. At a height of 10.0 m, the baseball, the baseball has a velocity of 24.5 m/s. a) Determine the mechanical energy of the ball at 10.0 m b) What is the mechanical energy of the ball at a height of 9.0 m?
