Dr. Haviland is looking at mental rotation data but he forgot to label his chart. The data shows reaction times for 700 ms, 1400 ms and 1200 ms. What are the MOST likely corresponding degrees of rotation that will match his data?

if the distance of separation begin two objects is doubled, is the gravitational force between the objects increased or decreased? by what factor?

A car accelerates uniformly from 0 to 15m/s in 5 s. Calculate acceleration.

A grandfather clock is "losing" time because its pendulum moves too slowly. Assume that the pendulum is a massive bob at the end of a string. The motion of this pendulum can be sped up by: a) decreasing the mass of the bob.
