A 5.0 g coin is placed 15 cm from the center of a turntable. The coin has static and kinetic coefficients of friction with the turntable surface of . The turntable very slowly speeds up to 60 rpm. Does the coin slide off?
Solution Step 1 of 5 Centripetal force is the force that acts on a body which is moving in the circular path and it is directed towards the center of the circular path on which the body is moving, as in the figure below;here as the coin on the turntable is rotating Centripetal force(F) of coin under uniform circular motion is given by equation F =cm r2 Where m and are the mass and angular velocity of the coin, r is the radius.
