The gure shows a truck accelerating to the right. There is a crate on the truck. There is friction between the surface of the truck's bed and the crate? but it is not strong enough to keep the crate in place on the truck. The crate starts to slide and the friction force is kinetic friction. The direction of the crate's acceleration will be: {Think carefully about the direction ofthe friction forcehow it is determined by the relative motion between the two surfaces-and then think what Newton's 2nd Law says about the direction of the acceleration and the net force.) 0 to the right. Q up. 0 down. i The crate will not have an acceleration. O to the left
