The chain on a chain saw is driven by a sprocket r = 3 cm in
radius. If the
chain is L = 140 cm long and makes one revolution in T = 0:3 sec,
what
is the angular velocity w (in rad/sec) of the sprocket?
Answer
in general form first, as a formula w = ::: with L, r and
T in the
right-hand side, then substitute the given values and calculate
