Homework Statement[/B]A 5228 kg flatbed truck has a 226 kg crate resting on the level bed. If the static coefficient of friction is 0.27, what is the maximum acceleration the truck can achieve without the crate slipping off?
The Attempt at a Solution
i believe i need to find the force on each object. it would be 5228 x 9.8 and 226 x 9.8 but i am stuck there, especially with the static coefficient of friction. i do not understand that at all
