Problem: An obnoxious brat assigns his 0.0203-kilogram pet mouse Mickey the role of stunt mouse by stuffing him into a spring gun and shooting him up into the air at some angle. The gun\'s spring has a force constant of 92.1 N/m and is initially compressed 0.121 m. When Mickey reaches maximum height, he has a horizontal velocity with a speed of 2.35 m/s.
Part A: How high above his initial location in the gun does Mickey soar?
I want help to find how high above his initial location in the gun does Mickey soar and in case you are worried, a miniature parachute opens at this point and Mickey lands safely. The brat is slightly less obnoxious than we thought. Take g = 9.81 m/s2.
