A hiker of mass 66 kg is going to climb to the top of Mount Tam, which has an elevation of 2,574 ft.
A hiker of mass 66 kg is going to climb to the top of Mount Tam, which has an elevation of 2,574 ft.
If the hiker starts climbing at an elevation of 490 ft, what will their change in gravitational potential energy be, in joules, once they reach the top? Assume the zero of gravitational potential energy is at sea level.
ΔVg =?
