Question

A small coin is placed on a flat horizontal turntable.the turntable is observed to make three revolutions in 3.14s what is the speed of the voin when it rides without slipping

Answer 1

we will have to know how far is the coin from the center of the table.

From you given info, we find angular velocity omega

three revolution = 6$\pi$ radians

omega = 6 \pi / 3.14

omega =6 radians/s, approx

now speed of coin will be

v = omega * distance from center of rotation (we need this).

Hope this helps
