Question

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

    Consider a ball of mass 0.110 kg being spun in a horizontal circle of radius r-0.50 m, as shown to the right. When the ball reaches an angular velocity (o) of 2.00 rad/s, it is given a constant angular acceleration of a- 2.00 rads. You can assume that the radius of the circular path followed by the ball remains constant during this acceleration. After precisely 3.00 seconds of this angular acceleration, the ball breaks off the string (a) In what...
