A ski slope drops at an angle of 24 degrees with respect to the horizontal and is 500 m long. A 60 kg skier skis down from the top to the bottom of the slope.
A.) Determine the change in gravitational potential energy of the skier+earth system.
b.) If 20% of the gravitation potential energy of the system is transformed into the kinetic energy of the skier, how fast is the skier going at the bottom of the slope?
