My lab questions is stated as: "Derive equation for the acceleration using equations (2) and (3) from Introduction and Theory. Calculate the theoretical acceleration of the cart. Assume that the kinetic friction force Fk = ?k *Mg , where is M is the total mass of the cart and ?k the coefficient of kinetic friction which is set up as 0.07 in the virtual lab."

equation 2 from the lab manual is T -
