A wheel with radius 45 cm rolls without slipping along a horizontal floor as shown in figure. P is a dot pointed on the rim of the wheel. At time t1, P is at the point of contact between the wheel and the floor. At a later time t2, the wheel has rolled, through one–half of a revolution. What is the displacement of P during this interval?
- 90 cm
- 168 cm
- 40 cm
- data insufficient
Answer
(B) 168 cm
