  3. The table exerts a force of 150 N upward on the toy cart.
  4. The toy cart exerts a force of 15 N downward on the table.

10. Below is a diagram of a tug-a0war. Circle the correct word to complete the sentences that follow.

a. The forces shown are PUSHING/ PULLING forces.

b. The forces shown are acting in the SAME DIRECTION/ OPPOSITE DIRECTIONS.

c. The forces are EQUAL/ NOT EQUAL.

d. The forces are BALANCED/ UNBALANCED..

  1. A person is in a rolling chair at rest and throws a soccer ball to the right. The person in the will chair has a greater mass than the ball. What will happen to the person in the rolling chair and the soccer ball when they throw it?
  1. Out of the following, which would have the greatest acceleration? Explain your answer.
  1. 40 N – 5 kg
  2. 20 N- 5 kg
  3. 40 N- 10 kg
  4. 20 N- 10 kg
  1. A box is being pushed by two stellar science students, one on each side of the box. Dalton is pushing the box with a force of 10 N to the left. DeAndre is pushing the box with a force of 15 N to the right. Who is the stronger individual and what is the net force and direction on the box.
  1. During tug of war Janelle felt she was supergirl and attempted to beat Rameek. Janelle with one arm on the rope and the other at her side applied a 100 N force to the left, while Rameek applied a 100 N force with both hands to the right. What is the net force and direction on the rope?
  1. Janelle finally decided to take this seriously and put both hands on the rope and applied a 150 N force to the left, while Rameek still struggled with his 100 N force to the right. What is the net force and direction of motion.
