Question

A simplified model of a bicycle of mass M has two tires that each comes into contact with the ground at a point The wheel base of this bicycle the distance between the points of contact with the ground is w and the centre of mass C of the bicycle is located midway between the tires and a height h above the ground The bicycle is moving to the right but slowing down at a constant rate The acceleration has a magnitude a Air resistance may be ignored 40 W Assuming that the coefficient of sliding friction between each tire and the ground is u and that both tire are skidding sliding without rotating Express your answer in terms of W h M and g 41 What is the maximum value of u so that both tires remain in contact with the ground A W 2h C 2h W B h 2W D W h C What is the maximum value of a so that both tires remain in contact with the ground Wg Wg A 2h h hg 2W C B D h 2Wg h
