3. During the Scottish Highland games, famed hammer thrower Fergus Dunbroch is spinning the hammer along a circular path in preparation for the throw. The hammer has a mass of 7.3 kg (the mass of the cable is negligible). At one instant, the hammer thrower's angular velocity is 6.8 rad/s, and 0.9 seconds later the angular velocity of the hammer thrower has increased to 10.6 rad/s. a. If the radius of the hammer's rotation is a constant 1.5 m, what is the tangential velocity of the hammer at both instants in time? b. What is the average tangential acceleration of the hammer during the 0.9 s interval? c. What is the radial acceleration of the hammer when the thrower's angular velocity is 10.6 rad/s? d. What is the magnitude of the centripetal force required to maintain the hammer on it's curvilinear path when the thrower's angular velocity is 10.6 rad/s? 1. 2. 1000 3.
