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 30.00 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 is 1.90 cm?

Step-by-step solution Step 1 of 2 Use following formula to calculate the torque developed due to rotation. Here denotes the torque developed, is the moment of inertia and is the angular acceleration. Substitute and
