A ball with a mass of #80 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 #1/5 m# when the ball was released. How high will the ball go?
I tried this but check my maths.
We can consider:
So basically we can write:
We now use the kinematic relationship:
If we consider also the initial compression, the total vertical distance should be:
