Wile E. Coyote has a mass of 18.2 kg and he places himself at the end of a compressed spring. The spring has been compressed 2.1 m. The spring accelerates him to a velocity of 10.75 m/s and then stops pushing. Calculate the amount of elastic potential energy stored in the spring. Ignore friction and air resistance. Please show work thank you!
