A boy is sitting on the horizontal platform of a joy wheel at a distance of 5 m from the center. The wheel begins to rotate and when angular speed exceeds 1 rad/s, the boy just slips. The coefficient of friction between the boy and the wheel is `(g=10m//s^(2))`

A boy is sitting on a horizontal platform of joy wheel at a distance of 5 m from its centre .The joy wheel begins to rotate and when the angular speed exceeds 10 revolutions per minute, the boy just slip , the cofficient of friction between ( g=10m//s^(2))

A boy is sitting on a horizontal platform in the shape of a disc at a distance of 5m from its centre. The boy begins to slip when the speed of wheel exceeds 10 rpm. The coefficient of friction between the boy and platform is: (g = 10 ms^(-2))

A coin kept at a distance of 5 cm from the centre of a turntable of radius 1.5 m just begins to slip when the turntable rotates at a speed of 90 r.p.m. Calculate the coefficient of static friction between the coin and the turntable [g = 9.8 m//s^(2)]

Two particles of mass M=3kg each are kept on a horizontal circular platform on two mutually perpendicular radii at equal distance R=1m from the centre of the table. The particles are connected with a string,which is just taught when the platform is not rotating.Coefficient of friction between the platform and block is mu=0.4 .Then the maximum angular speed (omega in frac{rad}{sec} ) of platform about its centre so that the blocks remain stationary relative to platform is (take g=10.m/s^(2) )

A boy (30 kg) sitting on his horse whips it. The horse speeds up at an average acceleration of 2.0 m/s^2 . A. If the boy does not slide back, what is the force of friction exerted by the horse on the boy? b.If the boy slides back during the acceleration, what can be said about the coefficient of static friction between the horse and the boy. Take g = 10 m/s^2
