Lab 24A: Friction and Newton\'s Laws Introduction Input I Elastic Bumper The photogate is used to measure the acceleration of the Friction Tray as it is being pulled by the falling mass Setup 1. The Elastic Bumper should be placed about 15 cm from the end of the track as shown in Figure 1. The Clampo-on Pulley should have the pulley in the upper set of holes as shown. 2. The Photogate Bracket (see Figure 2) is cantilevered out over the end of the track, Note that the bracket is put on \"reversed so that it doesn\'t Figure 1. Measuring 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. If you don\'t have a level, you can Photogate use a PAScar, and adjust the track so the cart doesn\'t roll. 5. Determine the mass of the tray before attaching string Record value below.

Solution

Purpose : To determine the acceleration of a fricion tray using a rope and pulley arrangement.

For conclusion we need to compare the calculated results with the known results. The known results could be from some other source. We can say that our results are matching with the known values of acceleration
