A cyclist starts form centre ` O` of a circular park of radius ` 1 km` and moves along the path ` OPRQO` as shown Fig. 2 (EP).15. If he maintains constant speed of ` 10 ms^(-1)`, what is his acceleration at point (R )in magnitude and direction ?
.

Text Solution

Verified by Experts

Centripetal acceleration
`a_(c)=(v^(2))/(r)=((10^(2))/(1000))=0.1 ms^(-2)`
The direction is along RO , radially inwards .
