Mass and Motion A cat with a mass of 5 kg is sitting on a skateboard.
A rat with a mass of 0.5 kg is sitting on an identical
skateboard.
2. If you apply the same force to push each
skateboard, will the cat or the rat accelerate the
fastest? Explain.

When you turn on a battery-operated device, an electrical circuit is

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

At the negative terminal of the battery the electron has electric potential energy. what happens to this energy as the electron jumps from the negative to the positive terminal?
