Question
1. I ran a computer simulation of a ball bearing (steel sphere, about 5 mm in diameter) falling under the force
of gravity through (1) water and (2) purified honey. The downward velocity of the ball bearing (normalized
to unity; "AU" = arbitrary units) is plotted against time below. (a) Which curve is the simulation of the ball
bearing falling through water? (b) Which curve is the simulation of the BB falling through honey? (c) Draw
and label a curve that represents what the velocity-vs.-time profile might be if the BB were falling through
air. (d) Draw and label a curve that represents what the velocity-vs.-time profile might be if the BB were
falling through a perfect vacuum.
