1. The problem statement, all variables and given/known data Useing atwood machine, determine acceleration, knowing weight of mass to be pulled and mass pulling, distance mass travels, and information provided by photogate[which we don't understand what exactly this information is] 2. Relevant equations Unknown... 3. The attempt at a solution Please help. My lab group is at a complete loss on the application of this section, we have no idea where we need to start. We have our data collected, but we don't know how acceleration can be found.
