The height is
The spring constant is
The compression is
The potential energy in the spring is
This potential energy will be converted to kinetic energy when the spring is released and to potential energy of the ball
Let the height of the ball be
Then ,
The potential energy of the ball is
The mass of the ball is
The acceleration due to gravity is
The height is
A ball with a mass of #70 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #49 (kg)/s^2# and was compressed by #7/6 m# when the ball was released. How high will the ball go?
