A disc of 8.0 cm in radius rotates at a constant rate of 1200 revolution per minute about its central axis. Calculate the
(a) angular velocity in rad s?

(b) tangential speed at a point 3.0 cm from its centre.

(c) distance travelled by a point at the edge of the disc in 2.0 s.

(d) angular acceleration if the disc stop rotating at 3.0 s.

Could someone . i have tried to solve myself but my calculation is off

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
