Acart consists of a body and four wheels on frictionless axles. the body has a mass m. the wheels are uniform disks of mass m and radius r. the cart rolls, without slipping, back and forth on a horizontal plane under the influence of a spring attached to one end of the cart. the spring constant is k. taking into account the moment of inertia of the wheels, find a formula for the frequency of the back-and-forth motion of the cart

Look it up you feel me
