Question
Someone frequently throws a tennis ball for their dog to chase.
Throughout the throwing motion, the
radians/s, and the radius of rotation of the ball is 63.0 cm.
One day they decide to test out a ball-throwing tool which effectively
extends the radius of rotation by an extra 36 cm. Assuming all other
variables are equal, how much faster (in m/s) can they throw the ball
when they use the launcher compared to when they don't?
Express your answer to 2 decimals, and don't include units
+.
