A small coin is placed on a fiat, horizontal turntable. The turntable is observed to make exactly three revolutions in 3.3 s. (a) What is the speed of the coin when it rides without slipping at a distance of 5.2 cm from the center of the turntable? (b) What is the acceleration (magnitude and direction) of the coin in part (a)? (c) What is the force of friction acting on the coin in part (a) if the coin has a mass of 1.7 g? (d) What is the coefficient of static friction between the coin and the turntable if the coin is observed to slide off the turntable when it is more than 12 cm from the center of the turntable?

Question

Jitender Pal · Answer

Therefore, the acceleration of the coin is 1.61 m/s².

Therefore, the force of friction acting on the coin is 2.7 x 10^-3 N.

Therefore, the static coefficient of friction between the coin and the turntable is 0.58 .
