Q31-32: Amar exerts an average net torque of 100 N-m when throwing a 7.27-kg hammer on a 1-m wire about its axis of spin. The radius of gyration of the hammer about the spin axis is 0.5 m. 31. If the hammer is released with a linear velocity of 28 m/s, what is the centripetal force that is exerted on the thrower by the hammer at the instant before release? 32. If the hammer is not spinning at the start of Amar's throwing action, and the throwing action lasts for 0.2 s, how fast is the discus spinning when Amar releases it?
