<p>Student: Ms. Elbein & Ms. Townsend Physics, ______Due Date: 1. There is a ball, suspended by a cable. It is not moving. a. Draw a force diagram for this ball.</p><p> b. The downward force on the ball, or its weight, is the product of the ball’s mass and 9.81 (which is the acceleration due to gravity). What is the magnitude of the downward force on the ball? (weight = m x 9.81)</p><p> c. What is the net force acting on the ball?</p><p> d. What is the tension in the cable? (Fnet = tension – weight)</p><p>2. You push a table across the floor to the right with a force of 20 N (this is the force of your push). The force of friction between the table and the floor is 4 N. The weight is 400 N, and the mass is 41 kg. a. Draw a picture AND then a force diagram for the table.</p><p> b. What is the net force acting on the table? (Fnet = applied – friction)</p><p> c What is the acceleration of the table? ()</p><p>Aim/Purpose of this assignment: To practice the quantitative versions of forces. Student: Ms. Elbein & Ms. Townsend Physics, ______Due Date: 3. Bugs Bunny and Daffy Duck push Elmer Fudd to the right with a 100 N force each, but he ain’t gonna do it. Elmer keeps his feet on the ground, creating 25 N of friction. Elmer Fudd’s weight is 750 N. a. Draw a picture and then a force diagram of Elmer Fudd.</p><p> b. What is the net force on Elmer Fudd? (Fnet = applied + applied – friction)</p><p> c. What is Elmer Fudd’s acceleration? (Step 1: Find the mass. Step 2: Find the acceleration)</p><p>4. </p><p>5. An elevator is moving up at a constant velocity, as illustrated in the diagram below: The passenger has a mass of 85 kg. a. Construct a force diagram for the passenger. </p><p>Aim/Purpose of this assignment: To practice the quantitative versions of forces. Student: Ms. Elbein & Ms. Townsend Physics, ______Due Date: </p><p> b. What is the weight of the person? (weight = m x 9.81)</p><p> c. What is the net force acting on the person?</p><p> d. Calculate the normal force on the passenger. (Use your answers to C and D.)</p><p>6. Calculate the blanks for the elephant. Fgrav = weight = m x 9.81 Fnet = m x a</p><p>Fnet = Fair – Fgrav </p><p>7. Calculate the blanks for the cart. Fgrav = weight = m x 9.81 Fnorm = Fgrav </p><p>Aim/Purpose of this assignment: To practice the quantitative versions of forces. Student: Ms. Elbein & Ms. Townsend Physics, ______Due Date: </p><p>Fnet = m x a Fnet = which force?</p><p>8. Calculate the blanks for the coffee filter. Fgrav = weight = m x 9.81 Fair = Fgrav </p><p>9. Calculate the blanks for the sled. Fgrav = weight = m x 9.81 Fnorm = Fgrav </p><p>Fnet = m x a Fnet = which force?</p><p>Aim/Purpose of this assignment: To practice the quantitative versions of forces.</p>
