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...
A disk with mass m = 8.8 kg and radius R = 0.36 m begins at rest and accelerates uniformly for t = 16.5 s, to a final angular speed of ω = 31 rad/s. 1) What is the change in rotational energy of the disk? 2) What is the tangential component of the acceleration of a point on the rim of the disk when the disk has accelerated to half its final angular speed? 3) What is the magnitude...
