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 is JV, and the centre of mass C of the bicycle is located mid way between the tires and a height h above the ground.The bicycleis moving to the right,but slowing down at a constant acceleration a. Air resistance may be ignored. Assuming that the coefficient of sliding friction between each tyre and the ground is ` mu` and that both tyres are skidding (sliding without rotating). Express your answer in terms of w,h,M and g .
What is the maximum value of `mu` so that both tires remain in contact with the ground :

Options

A. `W//2h`
B. `h//2W`
C. `2h//W`
D. `W//h`

Answer

A
