# Question: In a high speed chase a policeman s car bumps a criminal s

In a high-speed chase, a policeman’s car bumps a criminal’s car directly from behind to get his attention. The policeman’s car is moving at 40.0 m/s to the right and has a total mass of 1800 kg. The criminal’s car is initially moving in the same direction at 38.0 m/s. His car has a total mass of 1500 kg. Assuming an elastic collision, determine their two velocities immediately after the bump.

Fig. 6.36 shows a bird catching a fish. Assume that initially the fish jumps up and that the bird coasts horizontally and does not touch the water with its feet or flap its wings. (a) Is this kind of collision (1) elastic, ...A 1.0-kg object moving at collides elastically with a stationary 1.0-kg object, similar to the situation shown in Fig. 6.37. How far will the initially stationary object travel along a 37o inclined plane? (Neglect friction.) Show that the fraction of kinetic energy lost in a ballistic-pendulum collision (as in Fig. 6.35) is equal to M/(m + M). Locate the center of mass of the system shown in Fig. 6.39 (a) If all of the masses are equal; (b) If m2 = m4 = 2m1 = 2m3; (c) If m1 = 1.0 kg, m2 = 2.0 kg. m3 = 3.0 kg and m4 = 4.0 kg.
