A thin, light string is wrapped around the rim of a 4.10 kg, solid, uniform disk (similar to a puck on ice without friction) that is 26.5 cm in diameter. A person pulls (to the right direction) on the string with a constant force of 102.0 N tangent to the disk. The disk is not attached to anything and is free to move and turn. 1) Find the angular acceleration of the disk about its center of mass. Express your answer in radians per second squared. 2) Find the linear acceleration of its center of mass. Express your answer in meters per second squared. 3) If the disk is replaced by a hollow, thin-walled cylinder of the same mass and diameter, what will be the angular acceleration of the disk about its center of mass? Express your answer in radians per second squared. 4) If the disk is replaced by a hollow, thin-walled cylinder of the same mass and diameter, what will be the linear acceleration of its center of mass?

A grindstone in the shape of a solid disk with diameter 0.520 mm and a mass of 50.0 kg is rotating at 800 rev/minrev/min . You press an axe against the rim with a normal force of 160 NN (see the figure below (Figure 1)), and the grindstone comes to rest in 8.00 ss. There is negligible friction in the bearings. Find the coefficient of kinetic friction between the axe and the grindstone.
A 1.5 kg block is connected by a rope across a 50-cm-diameter, 2.0 kg pulley, as shown. There is no friction in the axle, but there is friction between the rope and the pulley; the rope doesn’t slip. The weight is accelerating upward at 1.2 m/s2. What is the tension in the rope on the right side of the pulley?
A 7-kg mass (m1) hangs from a cord that runs through a pulley and back down to attach to a 6-kg mass (m2) that is hanging from the other side.

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total gravitational force on the body, F, is supported by the force n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and e when F, = n = 675 N. (For e, enter the smaller of the two possible values between 0° and 90°.) Achilles tendon Tibia 15.0° 18.0 cm 25.0 cm T = N R = N Need Help?

A van with mass m = 1000 kg is driving around a circular curve of radius r = 950 m when it begins to rain. The coefficients of static friction between the track and tires is μd = 0.59 when dry and μw = 0.17 when wet. Write an expression for the maximum magnitude of the force of static friction Ff acting on the van if μs is the coefficient of friction. What is the maximum tangential speed that the van can take the corner at without slipping when dry in m/s? What is the maximum tangential speed when wet in m/s?

A uniform disk with mass m = 8.75 kg and radius R = 1.41 m lies in the x-y plane and centered at the origin. Three forces act in the +y- direction on the disk: 1) a force 315 N at the edge of the disk on the +x-axis, 2) a force 315 N at the edge of the disk on the -y-axis, and 3) a force 315 N acts at the edge of the disk at an angle 0 = 38° above the -x-axis. +y +x F3 IF, F2
