Answer:
The force of friction acts in the direction opposite to the direction of motion. If friction would have been applied to the skier it would have resulted in a lower velocity and less kinetic energy.
Explanation:
initial angular speed is given by 33.3 rpm


final angular speed is given by 78 rpm


now by using kinematics we will have
