How fast can a 4000 kg truck travel around a 70 m radius turn without skidding if its tires share a 0.6 friction coefficient with the ground?

Velocity of truck will be 20.287 m /sec

Explanation:

We have given mass of the truck m = 4000 kg

Radius of the turn r = 70 m

Coefficient of friction

Centripetal force is given  

And frictional force is equal to

For body to be move these two forces must be equal

So

+15-35=-20

going in opposite directions
