Textbook Question
Chapter 5, Problem 5.74AP
Why is the following situation impossible? A book sits on an inclined plane on the surface of the Earth. The angle of the plane with the horizontal is 60.0°. The coefficient of kinetic friction between the book and the plane is 0.300. At time t = 0, the book is released from rest. The book then slides through a distance of 1.00 m, measured along the plane, in a time interval of 0.483 s.

A mass m slides up an incline (with = 32.1 degrees above the horizontal) until it stops momentarily because of friction. The coefficient of static friction between the mass and incline is 0.9; the coefficient of kinetic friction between the mass and incline is 0.4. At a given instant, the mass is moving with speed of 4.3 m/s up the incline. How far beyond this point along the incline will the mass move before it comes to a stop?
A block is sliding down a ramp at an angle of 0 = 16° to the horizontal. Its initial
speed is 2.8 m/s. After sliding 13.6 m along the ramp, it comes to a rest. What is the
coefficient of kinetic friction, µ., between the block and the ramp?
Ө
One way to determine the coefficients of friction (μs and μk) between two surfaces is to use an incline plane. Consider a block of mass m = 2.0kg initially at rest at the top of the ramp. The angle θ is increased slowly. The object starts to slide down the ramp when θ = 40 . Once the block slides down, the angle is kept constant. The block travels along the ramp by distance d = 2.0 m in time t = 1.5 s.
(a) Determine the value of μs(b) Determine the value of μk
