Kristie is a 60 kg skier. At the start of a ski-slope that is at 30o to the horizontal, she crouches into a tuck. The surface is very icy, so that there is no friction between her skies and the ice. a) If Kristie starts from rest, what is her speed after travelling a distance 80 m on the ice? b) Snow condition changes at the end of ice path so that Kristie continues down the slope with a constant velocity. Determine the co-efficient of kinetic friction between her skies and the path with changed snow condition.

A skier (m = 60 kg) initially at rest skis down a (frictionless) hill from an altitude of 75 m. When she reaches the bottom (a flat horizontal surface with µk = 0.2) she slows down until she comes to a stop. (a) What is her speed when she reaches the bottom of the hill? (b) Over what distance at the bottom does she come to a stop?

A skier with a mass of 75kg starts from rest at the top of a slope which is 110m tall and skis to the bottom. Hint: you must use conservation of energy to solve both parts of this problem. a. What is the skier’s speed at the bottom of the slope if there is no friction? b. If the speed of the skier at the bottom of the slope is actually 20m/s, how much work is done by friction?

In the figure, a T bar ski tow pulls a skier up a hill inclined at 10 degrees above horizontal. The skier starts from rest and is pulled by a cable that exerts tension T at an angle of 30 degrees above the surface of the hill. The mass of the skier is 60kg and the effective coefficient of kinetic friction between the skis and the snow is 0.100. What is the maximum tension in the cable if the starting...

Suppose a ski resort bases revenue projections on the assumption that an average skier skis four times per year. To evaluate the validity of this assumption, a random sample of 63 skiers is drawn and each is asked to report the number of times he or she skied last year. The sample average is 4.38 times. Assuming the population standard deviation is 2 times, can we infer at a 10% significance level that the resort’s assumption is wrong? a) Set...

5: A skier, m = 65 kg, glides on a perfect hill, 10 m high, no friction. However, at the bottom is a spring, k = 1500 N/m , system to stop the skier. A silly technique I will grant you. The spring is not perfect, it loses 800 J of energy every time the spring fully compresses or extends. Now we will have to assume the spring never extends past its equilibrium position. A: What is the speed of...
