JEE MainPhysicsCircular MotionMCQ+4 / −1
A point PPP moves in counter-clockwise direction on a circular path as shown in the figure. The movement of PPP is such that it sweeps out a length s=t3+5,s = {t^3} + 5,s=t3+5, where sss is in metres and ttt is in seconds. The radius of the path is 20m.20m.20m. The acceleration of ′P′'P'′P′ when t=2st=2st=2s is nearly. AIEEE 2010 Physics - Circular Motion Question 65 English
