To develop muscle tone, a woman lifts a 2.50 kg weight held in her hand. She uses her biceps muscle to flex the lower arm through an angle of 60.0°. (a) What is the angular acceleration (in rad/s2) if the weight is 24.0 cm from the elbow joint, her forearm has a moment of inertia of 0.250 kg. m2, and the net force she exerts is 800 N at an effective perpendicular lever arm of 2.20 cm? (Ignore gravity) rad/s² (b) How much work (in )) does she do?
