Answer :
Potential energy (PE) = m g h
Where:
m = mass = 425 kg
g = gravity = 9.8 m/s2
h = height
PE = 72250J
Replacing:
72250 J = 425 kg * 9.8 m/s^2 * h
Solve for H
72250 J/ (425 kg * 9.8 m/s^2) = h
h = 17.35 m
Potential energy (PE) = m g h
Where:
m = mass = 425 kg
g = gravity = 9.8 m/s2
h = height
PE = 72250J
Replacing:
72250 J = 425 kg * 9.8 m/s^2 * h
Solve for H
72250 J/ (425 kg * 9.8 m/s^2) = h
h = 17.35 m
