7. Calculate the magnitude of the net torque on the disk refers to the rotation axis (the black solid dot) shown in the figure to the right. 4.0 cm 30 N 20 N

If point on a front wheel of the bicycle tire completes exactly eight turns, what can be said about the linear and angular acceleration of point . a. Only the angular displacement is zero. b. Only the linear displacement is zero. c. Neither is zero. d. Both are zero.

9. Doja sits on the outer part of a carousel, and Megan sits midway between the center and the rim. The carousel makes one complete revolution every 3 seconds. Megan's tangential velocity is: a. twice of Doja's b. the same as Doja's c. half of Doja's d. four times Doja's

A, B and C are rotating disks. A rotates at constant angular velocity, B at increasing angular velocity and C at decreasing angular velocity. There is a radial and a tangential acceleration in the case of a. Both A and B. b. None of A, B or C. c. Both B and C. d. Both A and C. e. All of A, B and C.

Need help on these two questions

3. A rod with a mass of 10kg and a total length of 2 meters that can spin about an axis through its center ( I = ML2 ) receives a constant force of 5 N on one of its ends. As the rod spins, the 12 force will maintain the same strength and orientation i.e., angled at 60 degrees with respect to the rod. The rod is initially at rest. Total Length Axis 60 deg F, a. How many radians does the rod sweep through after a period of 10 seconds? b. What is the speed of a point on the end of the rod at that same moment?

1. Refer to figure 1. Calculate the rotational velocity (magnitude and direction), frequency, period, tangential velocity. radius Figure 1: Radius of rotation is 0.500 m and spins at 120 rpm.
