Answer:

Minimum speed will be equal to 2.213 m/sec

Explanation:

We have given radius of the r = 2 m

Coefficient of friction $\mu =0.25$

At minimum speed frictional force will be equal to centripetal force

So $\mu mg=\frac{mv^2}{r}$

$\frac{v^2}{r}=\mu g$

$v=\sqrt{\mu rg}=\sqrt{0.25\times 2\times 9.8}=2.213m/sec$

So the minimum speed will be equal to 2.213 m/sec
