A cannon fires a cannonball at an angle 30 degrees above the horizontal, which flies through the air. It is fired with a force of 1000 N, and the cannonball is 10 kg. The initial height of the cannonball after firing is 0 m.

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.
