Problem 1 A disk 25.00 cm in radius rotates at a constant rate of 1 200 rev/min about its central axis. Determine; (a) its angular speed in radians per second and the tangential speed at a point 15.00 cm from its center. (b) the radial acceleration of a point on the rim, and the total distance a point on the rim moves in 6.00 S.
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...
1 2 3 4 56 A uniform disk of mass 0.76 kg and radius 5.7 cm is mounted in the center of a 10 cm axle and spun at 795 rev/min. The axle is then placed in a horizontal position with one end resting on a pivot. The other end is given an initial horizontal velocity such that the precession is smooth with no nutation. 1) (a) What is the magnitude of the angular velocity of precession? rad/s Submit You...
