Unformatted text preview: 3. A 75.0kg football player (#56) moving eastward at 5.00m/s when he collides with and holds on to an 80.0kg ball carrier (#22) running northward at 4.00m/s. Together they move at 3.89m/s just after the collision. This is not enough information to answer the simple question, “What is the force that #56 exerts on #22?” (a)What additional information do you need? (b)Even if you can’t find the force the #56 exerts on #22, what can you say about the force the #22 exerts on #56? (c)What does this tell you about the total momentum of #56 and #22? 4. I saw the sketch below in the newspaper a while back. The author of the associated article explained the benefits of using cable barriers instead of concrete on highways in simple terms. Now, you need to explain the same thing using the principles of physics....
