A ball with a mass of 300 g300g is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of 54 (kg)/s^254kgs2 and was compressed by 7/6 m76m when the ball was released. How high will the ball go?

h=12,49 " meters"h=12,49 meters

Explanation:

E_p=1/2*K*Delta x^2
E_p=1/2*54*(7/6)^2

E_p=27*49/36

E_p=36,75J" stored energy for spring"

m*g*h=36,75
m=300" gr"=0,3" kg"
g=9,81 N/(kg)

h=(36,75)/(0,3*9,81)

h=(36,75)/(2,943)

h=12,49 " meters"
