Chapter 8, Problem 82PP
Referring to Example 8-17 suppose we would like the landing speed of block 2 to be increased to 1.50 m/s (a) Should the coefficient of kinetic friction between block 1 and the tabletop be increased or decreased? (b) Find the required coefficient of kinetic friction for a landing speed of 1.50 m/s Note that m1 = 2.40kg, m2 = 1.80 kg, and d = 0.500m.

Now we will consider a slighty different scenario related to example 8-17.
Find the required coefficient of kinetic friction for a landing speed of 1.64.
A box with a mass of 7.24 kg is held at the top of frictionless inclined plane of length L = 10.9 m and an inclination angle 0 = 26.9 degrees above the horizontal. The box is released from rest and stops at a distanced = 22.62 m from the bottom of the inclined plane along the rough horizontal surface. What is the coefficient of kinetic friction between the box and the rough horizontal surface?
An object with a mass of 10 kg is initially at rest at the top of a frictionless inclined plane that rises at 30° above the horizontal. At the top, the object is initially 8.0 m from the bottom of the incline, as shown in the figure. When the object is released from this position, it eventually stops at a distance d from the bottom of the inclined plane along a horizontal surface, as shown. The coefficient of kinetic friction between the horizontal surface and the object is 0.20, and air resistance is negligible. Find the distance d.
