A ball with a mass of #600 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #16 (kg)/s^2# and was compressed by #3/5 m# when the ball was released. How high will the ball go?
The height is
The energy stored in the spring will be converted to kinetic energy and this will give the initial speed of the ball.
Spring constant is
Energy in the spring
Kinetic energy is
We apply the equation of motion
To find the greatest height
