A pitcher throws a baseball from the pitcher’s mound to home plate in 0.562 s. The distance is 18.4 m. What was the average speed of the baseball?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
