A baseball is thrown at a 22.5° angle and an initial velocity of 65 m/s. What will be its horizontal and vertical velocity?*

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.
