A 39.2-cm diameter disk rotates with a constant angular acceleration of 2.8 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at this time. (a) Find the angular speed of the wheel at t 2.30 s. rad/s 2.30 s (b) Find the linear velocity and tangential acceleration of P at t...
A large solid disk of radius 0.56 m freely rotates about a vertical frictionless axis at an initial angular speed of 8.3 rad/s. A small friction brake is used to bring the disk to rest in a time of 4.5 s by pressing the brake radially inward against the rim of the disk with a constant force of 36 N as shown in the figure below. The coefficient of friction between the brake and the disk is 0.4. Side View...

3. A circular disk of radius 2 cm slides at a speed 10 cm/sec in the direction of (t) (3, 4). As it slides it spins counterclockwise at 3 revolutions per second. Initially (ie, t = 0), the center of the disk is at the origin, O- (0,0). Find parametric equations for the trajectory of the point P on the edge of the disk, which is initially at (2,0). (Hint: Split the motion into sliding(i.e. translation) of the center and...
