Question

Using two spring scales, students pull on opposite sides of a dynamic cart at rest. 7 Newtons of force is pulling left and 5 Newtons force is pulling right. Describe the motion of the cart? A) The cart will move to the right. B) The cart will move to the left. C) The cart will not move. D) The cart will move up.

Answer 1

Answer is: B) The cart will move to the left.

A newton (N) is the International unit of measure for force.

One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in direction of the applied force.

The cart will move to the left by the force of 2 newton.

F(cart) = 7 N - 5 N.

F(cart) = 2 N to the left.
