Lab 24A: Friction and Newton's Laws Input The photogate is used to measure the acceleration of the Friction Tray as it is being pulled by the falling Setup 1. The Elastic Bumper should be placed about 15 cm from the end of the track as shown in Figure 1. The Clamp-on Pulley should have the pulley in the upper set of holes as shown Pulley 2.The Photogate Bracket Isee Figure 20 is cantilevered out over the end of the track. Note that the bracket is put on reversed so thatit doesnt ure 1. Maas Sliding Friction key into the track. This allows you to angle the bracket and Photogate 3 Plug the Photogate into Digital input 1 4, Level the track, ryou dont have a level, you can use a PAscar, and adust the track so the cart doesn't roll. 5 Determine the mass of the tray before attaching string Record value below. Use the tray with the cork surface. Bracket Mtay (with mass 346 g Cgure 2. Reversed Bracket Friction Tray ned but not written by Jon Hanks

Explanation / Answer
