Question

an object with a mass of 70kilograms is supported at a height 8meters above the ground. what's the potential energy of the object with respect to the ground ?(a)560J(b)2,058J(c)5,488J(d)3,430J

Answer 1

Gravitational Potential Energy = mgh (m=mass; g=gravitational force(9.8N/kg); h = height)

Ug = (70kg)(9.8N/kg)(8m) = 5488J which is C.)
