The coefficient of static friction between a block and a horizontal floor is 0.37, while the coefficient of kinetic friction is 0.10. The mass of the block is 3.8 kg and it is initially at rest. Once the block is sliding, if you keep pushing on it with the same minimum ...

PHYSICS
A large stone block has been loaded in the bed of a dump truck. The bed is slowly raised until it makes an angle of 30 degrees with the horizontal; at this point, the block starts to slide downward. What is the coefficient of static friction between the block and the truck bed...
