Question

A man carrying a monkey on his shoulder does cycling smoothly on a circular track of radius 9 m and completes 120 resolutions in 3 minutes. The magnitude of centripetal acceleration of monkey is ( in m / s 2 ) :

TestHub · Accepted Answer

​ Given : R = 9 m , 120 revolution in 3 min ω = 3 min . 120 Rev . ​ = 3 × 60 sec 120 × 2 π rad ​ = 3 4 π ​ rad / s a centripetal ​ = ω 2 R = ( 3 4 π ​ ) 2 × 9 = 16 π 2 m / s 2 ​
