The mass of the skier, including his equipment, is 75kg. In the ski race, the total vertical
change in height is 880 m.
Calculate the decrease in the gravitational potential energy (g.p.e.) of the skier

Respuesta :

The gravitational potential energy

gpe = mgh

[tex]\tt gpe=75\times 9.8\times880=646,800~J[/tex]
