Question

A 5 kg ball takes 21.0 seconds for one revolution around the circle. What's the magnitude of the angular velocity of this motion?

Answer 1

Answer #1

Angular speed is rev per dec.

Hence time tsken for one revolution is 21 sec.

angular speed , w

w = 2pi/21

= 0.3 rads/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...
