A car of mass m=1000 kg starts moving from rest at a point A on a smooth horizontal surface. The car moves under the action of an engine force �⃗ of magnitude F=2000 N and of direction parallel to the surface. It reaches point O that is 70 m away from A, with a velocity �⃗!. a. Draw the free body diagram of the car. b. Using the Second Law of Newton, determine the acceleration of the car. c. Calculate the normal force acting on the car. d. Calculate the final velocity at O.
