A car starts moving from rest along the circumference of a horizontal circle of radius `R =49` m with a constant tangential acceleration `a_(t)=0.62 ms^(-2)`. The coefficient of sliding friction is `mu = 0.2`. What distancem will the car describe without sliding ?
[Hint : The car will start sliding when the frictional force attains its upper bound]

Answer

`s=(1)/(2)Rsqrt((mug//a_(t))^(2)-1)=60m`
