Example #1 A discus thrower moves the discus in a circle of radius 80.0 cm. At a certain instant, the thrower is spinning at an angular speed of 10.0 rad/s and the angular speed is increasing at 50.0 rad/s^ 2 . What is the tangential component of the acceleration of d g gp the discus at this time ? 2 rad A. 80 s 2 rad B. 89.4 s rad 4 0 2 C. 40 s
