A rock is moving around a circle as in the picture below. The rock is shown at an arbitrary time. Locations a, b, c, and d around the circle are reference locations. The coordinate system shown is positive up for the movement of the shadow. The radius of the circle is 8.7 m. The time for the rock to make one revolution is 5.7 sec. Find the value of the angular velocity (in rad/s). Give only the number in the...

6. A ball is tied to the end of a cable of negligible mass. The ball is spun in a circle with a radius 2.00 m making 7.00 revolutions every 10.0 seconds. What are the (a) magnitude of the angular velocity in rad/s, (b) linear velocity in m/s, and (c) centripetal acceleration of the ball (in m/s')? Hint: 7 revolution divided by 10 seconds gives 0.7 rev/s, convert to rad/s
