The tension in the wire is equal and opposite to the resultant of the weight of the skier, the force up on the skier from the slope, and the friction between the skis and the snow.
if you increase the tension the skier may just speed up or may leave the snow. It depends on the mass of the skier and the slope.
A skier is pulled up a slope at constant speed. The tension in the wire pulls the skier with a force of 400N that acts at 40 degree to the slope.
1. Explain with reference to the forces acting on he skier why he travels at constant speed.
2.Describe two possible effects on the skier if the tension in the wire is suddenly increased.
