Two 0.50-kg carts resting on a low-friction track and connected by a spring are pushed toward each other. The left cart is pushed with a force of 10 N over a distance of 0.10 m, and the right cart is pushed with a force of 5 N over a distance of 0.04 m. Assume the spring has negligible inertia. You can convince yourself that the center of mass moved to the right by 0.03 m. Calculate the change in center of mass kinetic energy of the system consisting of the two carts and the spring.

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?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
