A hammer thrower accelerates the hammer (mass = 7.30kg) from rest within four full turns (revolution) and releases it at a speed of 28.0m/s. Assuming a uniform rate of increase in angular velocity and a horizontal circular path of radius 1.20m, calculate
(a) The angular acceleration,
(b) The (linear) tangential acceleration,
(c) The centripetal acceleration just before release,
(d) The net force being exerted on the hammer by the athlete just before release, and
(e) The angle of this force with respect to the radius of the circular motion.
