A 50 kg solid disk (I = ½ mr2) with a radius of r starts from rest and rotates about an axis through its center. It takes 30 rotations to reach an angular velocity of ω. Let ω = 24 rad/s Let r = 2.8 m Let θ = 32° What is the disk’s angular acceleration? (4 pts) How much time does it take to reach the final velocity? (4 pts) What is the net torque on the disk during...

Thanks so much for the help! Please show all work. A uniform solid disk with radius 9 cm has mass 0.5 kg (moment of inertia I = ½MR2). A constant force 12 N is applied as shown. At the instant shown, the angular velocity of the disk is 40 radians/s in the −z direction (where +x is to the right, +y is up, and +z is out of the page, toward you). The length of the string d is 13...

A wheel on a game show is given an initial angular speed of 1.22 rad>s. It comes to rest after rotating through 0.75 of a turn. (a) Find the average torque exerted on the wheel given that it is a disk of radius 0.71 m and mass 6.4 kg. (b) If the mass of the wheel is doubled and its radius is halved, will the angle through which it rotates before coming to rest increase, decrease, or stay the same?...

Q.3 A solid disk with a mass of 36 kg and a radius of 0.7 m is spinning around an axis through its center, it rotates with an angular speed of 3 full turns per second. You drop a 12 kg mass onto the disk at the edge, it sticks to the disk, reducing the angular speed to ws. Next you apply a 30 N force tangentially at the edge of the disk to slow it...

Problem 3 (25 pts) 01 The disk of mass m and radius R is rolling without slipping with angular speed W1 = 1 g/R on the horizontal surface when it encounters a step of height R/4. Assuming that the disk does not rebound when it hits the step and that it rotates about it, determine (a) the normal force between the disk and the corner immediately after the impact, R/4 (b) the percentage of energy lost during the impact, (c)...
