To develop muscle tone, a woman lifts a 2.00-kg weight held in her hand. she uses her biceps muscle to flex the lower arm through an angle of 60.0º. (a) what is the angular acceleration if the weight is 24.0 cm from the elbow joint, her forearm has a moment of inertia of 0.250 kg⋅m^{2} 2 , and the net force she exerts is 750 n at an effective perpendicular lever arm of 2.00 cm? (b) how much work does she do?
