7. Two billiard balls of equal mass, one blue and the other red, slide towards each other at 2.0m/s in opposite
directions towards each other. They collide head on and rebound both at 1.8m/s in opposite to their original
velocities, a s shown in the diagram below. Show how momentum is conserved in this collision.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
