In the Figure, a T-Bar Ski Tow Pulls a Skier

question 34

Multiple Choice

In the figure, a T-bar ski tow pulls a skier up a hill inclined at 10° above horizontal. The skier starts from rest and is pulled by a cable that exerts a tension T at an angle of 30° above the surface of the hill. The mass of the skier is 60 kg 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 acceleration is not to exceed 0.400 g?

Exterior Surface

The outermost boundary or layer of an object, material, or geometrical space that is exposed to the environment or another medium.

Hydrophilic

Describes molecules or substances that have a strong affinity for water, often because of the presence of polar groups.

Surface Carboxylate Groups

Functional groups on a solid surface where a carbon atom is double-bonded to an oxygen atom and single-bonded to another oxygen atom that is in turn bonded to a metal or hydrogen, typically present on surfaces for chemical reactivity.

Intermolecular Interaction

Forces that mediate between molecules, including hydrogen bonds, van der Waals forces, and dipole interactions, important in determining physical properties.
