A particle moves in a circle of radius 10 m. Its linear speed is given by `v=3t` where t is the lime in second and v is in `ms^(-1)`.Compute the centripetal and tangential acceleration at time t = 2s.

Text Solution

Verified by Experts

The linear speed at t = 2 s
`v=3t=6ms^(-1)`
The centripetal acceleration at t = 2 s is
`ac=(v^(2))/(r)=((6)^(2))/(10)=3.6ms^(-2)`
The tangential acceleration at `=(dv)/(dt)=3ms^(-2)`
