4. The wheel is composed of a 15kg hoop stiffened by four thin spokes, each with a mass of 2kg and radius r = 400mm. The wheel slips when a horizontal force P equal to or greater than 50N is applied to the wheel initially at rest. a) Calculate the static coefficient of friction. b) Calculate the linear velocity of the wheel's center after it has moved 2 meters with a constant force of P = 35N. P r 0
