Question Part 1: A deduction of 33% of the points for this question will be subtracted for each submission used beyond 4. You pull a cart by a rope attached to it along an unpaved road at constant velocity. Which of the following is applicable regarding the motion of this cart? (Select all that apply.) 1 The cart is not acted on by any outside forces in the direction of motion. The cart is moving with constant non-zero acceleration. The magnitude of the friction force acting on the cart equals the horizontal component of the pulling force. The net force acting on the cart in the direction of motion is zero. There can be no friction forces acting on the cart.
