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. Suppose she produces an angular acceleration of 28.5 rad/s2 and her lower leg has a moment of inertia of 0.7 kg⋅m2. What is the force, in newtons, exerted by the muscle if its effective perpendicular lever arm is 2.05 cm?
