10.A ball of 1 kg is shot vertically upward with 20 m/s from the ground. What is the kinetic energy (in Joule) on its way upward at a height of 10 meters above the ground? 11.A spring gun with spring constant 4000 N/m is compressed 10 cm from its natural length and then shoots a bullet out of the gun to 20 m/s. What is the mass of the bullet (in kg)? 12.A spring gun with spring constant 9800 N/m is compressed 10 cm from its natural length and then shoots a ball of 1 kg vertically upward. What is the maximum height the ball can reach (in meter)?
