A sphere of mass 25 gram is placed on a vertical spring. Spring is compressed by 0.2 ~m using a force 5 ~N . When the spring is relaxed, mass is reaching a height of ( g =10 ~m / s ^2 )

Step-by-step solution

Gravitational potential energy gained by the ball = Elastic potential energy in the spring aligned & mgh = 1 2 Fx & h = Fx 2 mg & = 5 0.2 2 25 10⁻³ 10 & =2 ~m aligned
