Question
The diagram given below shows a ski jump. A skier
weighing 60kgf stands at A at the top of ski jump. He
moves from A and takes off for his jump at B.
A
75 m
B
15 m
(a)Calculate the change in the gravitational potential
energy of the skier between A and B.
(b)lf 75% of the energy in part (a) becomes the kinetic
energy at B, calculate the speed at which the skier arrives
at B.
(Take g = 10 m s-²).
