A grindstone in the shape of a solid disk with diameter 0.520 m and a mass of 50.0 kg is rotating at 800 rev/min. You press an axe against the rim with a normal force of 160 N (see the figure below), and the grindstone comes to rest in 7.00 S. (Figure 1) Part A Find the coefficient of kinetic friction between the axe and the grindstone. There is negligible friction in the bearings Express your answer to three significant...
A block of mass M is attached to a wall by a massless spring with spring constant k. The block is allowed to oscillate on a frictionless surface. A second block of mass m is placed on top of the first block. The coefficient of static friction between the two blocks is his. What is the angular frequency of oscillation, and what is the maximum possible amplitude of oscillation such that the second block will not fly off?

One end of a light spring with force constant 290 N/m is attached to a vertical wall. A light string is tied to the other end of the horizontal spring. As shown in the following figure, the string changes from horizontal to vertical as it passes over a solid pulley of mass Mi the shape of a solid disk of radius R = 1.50 cm. The pulley is free to turn on a fixed smooth axle. The vertical section of...

A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass. At time t = 0 the mass is released from rest at a distance d = 0.35 m below its equilibrium height and undergoes simple harmonic motion with its position given as a function of time by y(t) = A cos(wt - φ). The positive y-axis...
