Answer to Question #17795 in Mechanics | Relativity for Rene Serna

Question

A hammer thrower is performing a throw. The hammer head is 2m away from the axis of rotation
(radius). During a preparatory phase, he rotates the hammer 4 times (4 revolutions) around the axis of
rotation (body). calculate angular displacement in degrees

Answer 1

Angular displacement equals to& zero for any whole number of revolutions (in our case we have 4 revolutions, so angular displacement is zero).
Answer: angular displacement equals to zero.
