A ski jumper has 1.2 ´ 10 J of potential energy at the top of the ski jump. The friction on the jump slope is?
A ski jumper has 1.2 ´ 10 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 jumper’s kinetic energy at the bottom of the jump?
a.
The kinetic energy will be greater than 1.2 x 104J.
b.
The kinetic energy will be less than 1.2 x 104J.
c.
The kinetic energy will be equal to the potential energy.
d.
Not enough information is given to determine what the kinetic energy will be
