A ski jumper has 1.2 x 10 4 J of potential energy at the top of the ski jump. The friction on the jump slope is small, but not negligible. What can you conclude about the ski jumpers kinetic energy at the bottom of the jump?

Respuesta :

Answer

kinetic energy will be less than 1.2×10^4 J

Explanation:

as some of this potential energy will be used to over come force of friction , hence by law of conservation of energy  , kinetic energy will be less than potential energy at top and will be less than 1.2×10^4 J
