This problem may sound very different from this week's experiment, but since free fall is also a one-dimensional motion with constant acceleration, the same physics covered in the experiment can be applied the same way.

For a base ball dropped from rest, what is its speed (in unit of LaTeX: \frac{m}{s} m s) after it falls 1.89m?

Long, long ago, on a planet far, far away, a physics experiment was carried out. First, a 0.250-kg ball with zero net charge was dropped from rest at a height of 1.00 m. The ball landed 0.450 s later. Next, the ball was given a net charge of 7.60 μC and dropped in the same way from the same height. This time the ball fell for 0.630 s before landing. What is the electric potential at a height of 1.00...
