A constant horizontal force of 10 N is applied at the centre of a wheel of mass 10 kg and radius 0.30 m . The wheel rolls without slipping on the horizontal surface, and the acceleration of the centre of mass is 0.60 m//s^(2) . a. What are the magnitude and direction of the frictional force on the wheel? b. What is the rotational inertia of the wheel about an axis through its centre of mass and perpendicular to the plane of the wheel?

A roller of mass 300kg and of radius 50cm lying on horizontal floor is resting against a step of height 20cm . The minimum horizontal force to be applied on the roller passing through its centre to turn the roller on to the step is

A solid cylinder wheel of mass M and radius R is pulled by a force F applied to the centre of the wheel at 37^@ to the horizontal. If the wheel is to roll without slipping, what is the maximum value of |F| ? The coefficients of static and kinetic friction are mu_(s)=0.40 and m_(k)=0.30. (sin37^@=3/5)
