A soccer player extends her lower leg in a kicking motion by exerting a force with the muscle above the knee in the front of her leg. She produces an angular acceleration of 30.0 rad/s2 and her lower leg has a moment of inertia of 0.750 kg·m2. What is the force exerted by the muscle if its effective perpendicular lever arm is2.00 cm?
