A ball with a mass of #360 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #24 (kg)/s^2# and was compressed by #5/3 m# when the ball was released. How high will the ball go?
The mass has to be put in kg:
We will use the conservation of energy.
The energy put by the spring:
The energy for the gravitation:
If we apply the conservation of energy to this situation:
We put the three equations together:
We isolate the height (y):
We take all the values of our situation and put them in there:
