Question

I need help with 2 problems:
1.) Calculate the potential energy of a 1,550 kg boulder on a hill that is 24 m. Here is the formula's to help: - PE=m*g*h or PE=1/2kx²

2.) Calculate the potential energy of a pinball machine with a spring that has a spring constant of 11 n/m and is compressed 0.15 m. Here are the formulas to help: PE=m*g*h or PE=1/2kx²

Answer 1

Answer:

1) 37.2×10power7 2)1237.5×10 power-4

Explanation:

1) P.E =mgh

m=1550

g=10 or 9.8

h=24m= 24×10 power3

PE=1550×10×24×10power 3

=37.2×10power7
