A 2000 kg car accelerates from rest under the actions of two forces. One is a forward force of 1140N provided by traction between the wheels and the road. The other is a 950N resistive force due to various frictional forces. Use the work-kinetic energy theorem to determine how far the car must travel for it's speed to reach 2.0m/s.

The force of air resistance acting on a falling object is approximated by the statement that it is proportional to the object's velocity and directed upward. If the object falls fast enough, will the force of air resistance eventually exceed the weight of the object and cause it to accelerate upward? explain......
