Potential Energy On Earth with a gravitational acceleration g, the potential energy stored in an object varies directly with its mass m and its vertical height h.
a. What is an equation that models the potential energy of a 2-kg skateboard that
is sliding down a ramp?
b. The acceleration due to gravity is g=-9.8 m/s2. What is the height of the ramp
if the skateboard has a potential energy of -39.2 kg m²/s2?
