My dog escaped out the front door and ran around the neighborhood for 15 minutes, then came home to lie down on the front porch. Which is greater, the distance the dog travelled or the dog’s displacement? Explain 16. A car goes form 0 to 60mph in 6 sec. What is its acceleration?

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.
