A constant horizontal force fapp of magnitude 10 N is exerted to a wheel having mass 10 kg and a radius 0.30m. The wheel rolls easily on the horizontal surface and the acceleration of its center of mass consists of a magnitude of 0.60m/s^2
i) In unit vector notation find out the friction force on the wheel.
ii) Find out the rational inertia of the wheel around the rotation axis through its center of mass.
