Question 2: (3pts) Indicate if the following forces are an action~reaction pair: ( a )The upward force on the cart from the track (the normal force) and the downward force of the cart. (b l The downward force on the rart from the gravitational attraction to the earth and the upward force of the earth dug to the cart. (c )The normal force on the cart from the track, and the upward force ofthe earth due to the cart. Question 3: (2pts) In this lab you are going to observe what happens to a frictionless cart when a string is connected to a hanging mass as shown in the picture. The tension (FT) in the string will accelerate the cart (m,) down the track by hanging different masses (m2) over the pulley, as shown in the picture. I 1103 Newton's Laws: Page | 15 DEPARTMENT OF PHYSICS AND ASTRONOMY APPALACHIAN STATE UNIVERSITY motion Refectory Cart m, hanging mass Draw free-body diagrams for both the cart and the hanging mass. Use m, to describe the cart, and m2 to describe the hanging mass. Be sure to follow the rules of how to draw a free-body diagram, including a reference frame Cart: Hanging Mass
