Which of the following is NOT true regarding the motion of the cart down the inclined if friction is neglected? Select one: O The higher the inclination, the greater the acceleration of the cart. O The higher the inclination, the time of travel of the cart shortens. O The acceleration of the cart is constant across different inclination angle. The additional mass on the cart does not affect its acceleration down the incline.
