I have an Ap Physics Class and my teacher doesnt have time to help me and i was wondering if anyone could help me with this problem.

A crate of mass 96 kg is loaded onto the back of a flatbed truck. The coefficient of static friction between the box and the truck bed is 0.14. What is the smallest radius of curvature, R, the truck can take, if the speed with which it is going around a circle is 2.9 m/s?

For the crate to go around the circle, its centripedal force must be less than or equal to the frictional force. By using this info, apply the formula (mv^2)/R then it's done.
