Professional Application Suppose a child drives a bumper car head on into the side rail, which exerts a force of 4000 N on the car for 0.200 s. (a) What impulse is imparted by this force? (b) Find the final velocity of the bumper car if its initial velocity was 2.80 m/s and the car plus driver have a mass of 200 kg. You may neglect friction between the car and floor.

Video Module 3 Notes Until now, we have been dealing with motion in mostly one dimension, and some in two dimensions. 3.1 Motion in two dimensions 3.1.1 Constant velocity in 2 dimensions (1:41) • In two dimensions velocity is broken into two components which can be expressed using the same equation for constant...
