Homework Help: Physics

Posted by Anne on Tuesday, November 22, 2011 at 2:07pm.

The drawing shows a model for the motion of the human forearm in throwing a dart. Because of the force applied by the triceps muscle, the forearm can rotate about an axis at the elbow joint. Assume that the forearm has the dimensions shown in the drawing and a moment of inertia of 0.080 kg m2 (including the effect of the dart) relative to the axis at the elbow. Assume also that the force acts perpendicular to the forearm. Ignoring the effect of gravity and any frictional forces, determine the magnitude of the force needed to give the dart a tangential speed of 5.2 m/s in 0.11 s, starting from rest.
