What is the acceleration if a 5 kg cart is pushed with 30 N of force?

What are the three ways that an object can accelerate

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.
