d. What is the acceleration of the box? (magnitude and direction) e. One of the forces on your free body diagram should be the normal force (make sure it is there!). For the normal force, what is the object, and what is the agent? f. Is there a Newton's third law force pair associated with the normal force acting on the box?

Please explain answers.

Analyzing Forces: Using Newton's 2nd Law A fireman has a mass of 75 kg. When the bell in the firehouse starts ringing, he slides down the pole with an acceleration of 3 m/s². What is the total force of friction acting on his body? 1. Identify the problem: What quantity are you being asked to find? What units will this answer be in? 2. Visualize and then sketch the problem. Draw arrows to illustrate the direction of the two forces acting on the fireman. Label these two forces by name. Do not use numbers yet. 3. These two forces act in opposite (+/-) directions and they will partially cancel. Assign the + value to the stronger force. The sum of these two forces is called the Net Force and it is the force which will actually move the fireman. Fill in the names of these two forces in the equation template below. (Hint: Remember that mass and weight are not the same.) Do not use numerical values yet: Net Force = + 4. Newton's 2nd Law gives us another equation for calculating Net Force: Net…

Free Response Questions ou push a grocery cart at an angle, down and to the left. The cart accelerates along a level floor in the prestince of friction effects between the cart and the floor. Draw force diagrams for you, the cart, and the floor/earth. Fully label all vectors. a. you floor/Earth cart b. While you are making the cart speed up, how does the size of the force you apply on the cart compare to the size of the force the cart exerts on you? Explain by referencing Newton's Laws c. While you are making the cart speed up, how does the size of the frictional force on the cart by the floor compare to the force applied on cart by you? Explain by referencing Newton's Laws While you are making the cart speed up, how does the size of the frictional force on the cart by the floor compare to the frictional force on you by the floor? Explain by referencing Newton's Laws Identify & list all of the Newton's Third Law pairs in your force diagrams.
