A discus thrower (in Greek, a Diskobolos ) accelerates a discus from rest through π radians accelerating it from angular velocity 0 to angular velocity 12 rad / s. We idealize her motion as circular with radius r = 0 . 65 m. The time of the throwing motion is 0 . 25 s. What is the net TRANSLATIONAL acceleration of the discus at the end of the throwing motion just before release? Give the direction of acceleration relative to the inward radial direction. a) 12 m / s 2 ; 15 ◦ . b) 99 m / s 2 ; 18 . 4 ◦ . c) 188 m / s 2 ; 13 . 9 ◦ . d) 144 m / s 2 ; 14 ◦ . e) 166 m / s 2 ; 32 ◦ . 011 qmult 10330 1 3 3 easy math: Waldo centrifuge, Waldo orbit fullmult Extra keywords: just rotational kinematics 15. ∗∗ Waldo’s back—you know, Waldo Pepper, the Playful Pig—just accept it.
