3. A discus thrower with an arm length of 1.2 m starts from rest and begins to rotate counterclockwise with an angular acceleration of 2.5 rad/s². P r-1.2m- a-2.5 rad/s a. How long does it take for his speed to get to 4.0 rad/s? b. What is the linear speed of the discus at 4.0 rad/s? c. What is the tangential acceleration of the discus thrower at this point? d. What is the magnitude of the centripetal acceleration of the discus thrown? e. What is the magnitude of the discus's total acceleration?
