a sphere with a mass of 3 kg slides along a rod which is bent in a vertical plane into a shape that can be described by the equation shown. when x=1.732m, the collar is moving along the rod at a speed of 5 m/s and the speed is increasing at the rate of 8 m/s^2 determine a) normal force exerted by rod on the particleb) coefficient of kinetic friction
