physcis question for the day
-
You toss a frisbee to your friend. It flies in a more-or-less straight line at a constant speed, reaching your friend after about 4 seconds. You estimate that when you released the frisbee, it was spinning around at a rate of about 4 rev/s (revolutions per second). You guess that the air drag slows the rate at which the frisbee spins by about 0.5 rev/s^2. You’d like to figure out how many revolutions the frisbee makes by the time your friend catches it. [NOTE: CAPA does not have units for revolutions, so this is just a dimensionless quantity—just a number].
