Below is a diagram with two arrows that represent the directions of two forces acting on a 3-kilogram ball. The arrows represent the direction the forces are being applied. Determine the newtons of force for each force.

• East = 10 newtons West = 7 newtons

• East = 12 newtons

  West = 8 newtons

• East = 5 newtons

  West = 2 newtons

• East = 13 newtons

  West = 13 newtons

At what point does the cart have the greatest amount of potential energy? At what point on the incline does the cart have the greatest amount of potential energy?

This is a two part question - remember your answer to this part.

• The cart has the greatest amount of potential energy at the highest point on the incline.

• The cart has the greatest amount of potential energy at the lowest point on the incline.

• The cart has the greatest amount of potential energy at the midpoint of the incline.

• The cart has the greatest amount of potential energy at the starting point of the incline.

Which statement below best supports your answer to part A of the question?

This is part two or the two part question.

• The cart has the most potential energy at the bottom of the ramp before it starts being pulled up.

• The cart rolling on the inclined plane does not affect the potential energy of the cart.

• The higher the cart rolls on the inclined plane, the more potential energy is accumulated.

• The higher the cart rolls on the inclined plane, the less potential energy accumulated.
