Question

4. The diagrams given below shows a ski jump. Asker
weighing 60 kgf stands at A at the top of ski jumap
He moves from A and takes off for his jump at
75 m
116 m
Fig. 2.20
(a) Calculate the change in the gravitational
potential energy of the skier between A and B.
(b) VF 75% of the energy in part (a) becomes
kinetic energy at B, calculate the speed at
which the skier arrives at B.
(Take g = 10 m s2)​

Answer 1

Answer:

sorry mate but where is your figure 2.20
