To keep homerun records and distances consistent from year to year, organized baseball randomly checks the coefficient of restitution between new baseball and wooden surface similar to that of of an average bat. Suppose you are in charge of making sure that no "juiced" baseballs are produced.(a) In a random test, you find one that when dropped from 2.0 m rebound 0.25 m.what is the coefficient of restitution for this ball?(b) what is the maximum distance home run shot you would expect from this ball, neglecting any effect due to air resistance and making reasonable assumption for bat speeds and incoming pitch speeds? Is this a "Juiced" ball,a "normal" ball, or a "dead" ball?
its looking for coefficient and maximum distance?
