A4.60 gg coin is placed 19.0 cmcm from the center of a turntable. the coin has static and kinetic coefficients of friction with the turntable surface of μs = 0.820 and μk = 0.440. the turntable very slowly speeds up.1. what is the angular speed in rpm when the coin slides off?

62.64 RPM.

Explanation:

Given that

m= 4.6 g

r= 19 cm

μs = 0.820

μk = 0.440.

The angular speed of the turntable = ω rad/s

Condition just before the slipping starts

The maximum value of the static friction force =Centripetal force

Therefore the speed in RPM will be 62.64 RPM.

it breaks and dirupture other materials and other sencews from the bottom

80cm/s.

24cm/s.

53.3cm/s.
