A baseball player is sliding into second base. Identify the forces on the baseball player.

Hey, everyone. So this problem is dealing with forces. Let's see what they're asking us. A wooden block is tossed so that it slides to the right on a bench list. All of the forces acting on the wooden block, we're told to assume negligible air resistance. So our multiple choice answers here are a kinetic friction and normal force. B weight, static friction and normal force, C, static friction and normal force, D weight, kinetic friction and normal force or E weight and normal force. So they are essentially asking us to draw our free body diagram and identify the forces acting on this block. So we have a, we have our bench and we have the block on the bench, it is tossed. So after it's let go, there are no forces acting on it to continue moving it uh to the right, but we do know that it's sliding to the right. So that's the direction of motion there. And so we have our friction force acting opposite to the direction of motion, we have our weight in the negative y direction and then our normal force will be in the positive Y direction. And so when we look at our multiple choice answers that aligns with answer choice D, we have weight, we have kinetic friction and we have our normal force. And now the reason why it is answer choice D and not B is because the block is moving, if the block was stationary, it would be static friction. But because we know that the block is sliding along the bench, that is our kinetic friction force. All right, that's all we have for this one. We'll see you in the next video.
