A54 gram coin sits on a horizontally rotating turntable. the turntable makes 1.0 revolution each second. the coin is located 10 cm from the axis of rotation of the turntable. the coin will slide off the turntable if it is located more than 14.4 cm from the axis of rotation. calculate the coefficient of static friction? show all the work

The coefficient of static friction is 0.578.

Explanation:

Given that,

Mass of coin = 54 gm

Revolution r = 1.0

Distance = 14.4 cm

We need to calculate the force when the coin located more than 14.4 cm from the axis of rotation

Using formula of centripetal force

Where, m = mass

R = radius

Put the value into the formula

We need to calculate the coefficient of static friction

Using formula of friction

Hence, The coefficient of static friction is 0.578.
