Chapter 4, Problem 91GP

A 72-kg water skier is being accelerated by a ski boat on a flat (“glassy") lake. The coefficient of kinetic friction between the skier's skis and the water surface is μ k = 0.25 (Fig. 4-74). (a) What is the skier’s acceleration if the rope pulling the skier behind the boat applies a horizontal tension force of magnitude FT= 240 N to the skier ( θ = 0°)? (b) What is the skier's horizontal acceleration if the rope pulling the skier exerts a force of Ft= 240 N on the skier at an upward angle θ =12°? (c) Explain why the skier's acceleration in part (b) is greater than that in part (a)

A car drives onto a section of the road which is covered in ice. The driver attempts to stop by hitting the brakes but the wheels lock and the car skids for another 60 m. Determine the coefficient of kinetic friction between the wheels and the ice if the initial speed of the car was 40 km/hr.
A 50 kg box is pushed with a force of 200 N along a horizontal surface. If the coefficient of friction between the box and the surface is 0.3, calculate the acceleration of the box. (Note: The gravitational acceleration can be assumed to be 9.8 m/s² unless stated otherwise.)
In Fig. 6-23, a sled is held on an inclined plane by a cord pulling directly up the plane. The sled is to be on the verge of moving up the plane. In Fig. 6- 28, the magnitude F required of the cord’s force on the sled is plotted versus a range of values for the coefficient of static friction ms between sled and plane: F1 = 2.0 N, F2 = 5.0 N, and m2 = 0.50. At what angle u is the plane inclined?
