A car is traveling up route 8 at 50 mph when he hits the gas and increases his speed 80 mph in 3 seconds. What is his acceleration in this time frame?

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.
