A particle is moving along a circuilar path of radius 5m. And with uniform speed 5 m/s. What will be the average acceleration when the particle completes half revolution:-

Text Solution

Verified by Experts

`t = (piR)/(v) = (pi xx 5)/(5) = pi sec`
`Delta vecv = (-5 hati) - (5hati) = -10 hati`
`veca_("avg") = (Delta vecv)/(t) = (-10hati)/(pi) rArr |veca _("avg")| = (10)/(pi) m//s^(2)`
