An obnoxious brat assigns his 0.0231-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 84.7 N/m and is initially compressed 0.137 m. When Mickey reaches maximum height, he has a horizontal velocity with a speed of 2.05 m/s. How high above his initial location in the gun does Mickey soar? (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.
1) Energy from spring = 1/2 . k . x^2 = 0.5 . 84.7 .
0.137^2
(2) Energy that is still KE = 1/2 . m . v^2 = 0.5 . 0.0183 .
2.05^2
(3) The rest of the energy must be in GPE = m . g. h = 0.0231 .
9.81 . h
Take (2) from (1) and the remainder = (3)

Mickey, a daredevil mouse of mass 0.0231 kg, is attempting to become the world's first "mouse cannonball." He is loaded into a spring‑powered gun pointing up at some angle and is shot into the air. The gun's spring has a force constant of 92.3 N/m and is initially compressed a distance of 0.147 m from its relaxed position. If Mickey has a constant horizontal speed of 2.17 m/s while he is flying through the air, how high ℎ above his...
