Solve for Part A?

(22%) Problem 3: 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 29 rad/s2 and her lower leg has a moment of inertia of 0.95 kg m A 100% Part (a) What is the force, in newtons, exerted by the muscle if its effective perpendicular lever arm is 1.8 cm?

Explanation / Answer

= 29 rad/s^2
I = 0.95 Kg/m^2

We know, Torque t = I*
t = F*r

Equating both equstions,
F*r = I*
Substituting Values,
F*(1.8*10^-2) = 0.95 * 29
F = 1530.5 N
