Paragraph: A simplified model of a bicycle of mass M has two tyres that each comes into contact with the ground at a point. The wheelbase of this bicycle (the distance between the points of contact with the ground) is w , and the center of mass of the bicycle is located midway between the tyres and at height h above the ground. Air resistance may be ignored. Case-2 : The bicycle is moving to the right, but slowing do

Options

  1. Aw g h
  2. Bw g 2 h
  3. Ch g 2 w
  4. D2 h g w

Correct answer

B. w g 2 h

Step-by-step solution

aligned & From (i), f = ma & mg = ma & a = g aligned aligned & = a g & w 2 h & a w g 2 h aligned
