1. The problem statement, all variables and given/known data I've got this lab I'm working on and I'm somewhat confused. We pushed a roller cart up an incline plane to determine acceleration and the such. Here is the graph. 2. Relevant equations The questions I have are: -Make a diagram of the track and show how to determine the angle of slope from your track height readings. calculate a value for Agsin(theta). Compare this to your overall acceleration. -From looking at the graph would you classify motion on an incline as accelerated or unacceleration motion? -How can you identify what interval the cart was freely moving? -Compare up and down values for acceleration. Why are they different? -From vales for angle, up, and down acceleration, determine the effective coefficient of friction for the motion cart. 3. The attempt at a solution 1. I assume this would be (9.8)(height/length) 2.Accelerated (negative) due to the force of friction acting against the cart which results in decreased velocity, aka varying acceleration. 3.Freely moving when the line is straight 4.Different due to slope of the incline? 5.getting to this one..... Can anyone guide me in the right direction?
