A skier of mass 83.3 kg comes down a slope of
constant angle 28� with the horizontal.
The acceleration of gravity is 9.8 m/s2 .
What is the force on the skier parallel to
the slope?
Answer in units of N
A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 24.0° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 60.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.160. Find the magnitude of the force that the tow bar exerts on the skier.
