Part 1: Predict the motion You may be familiar with an apparatus called the modified Atwood's machine. The purpose of this device is to annoy physics students demonstrate a how to apply Newton's laws to multi-object systems. You can see a picture of a modified Atwood's machine here: mass of disks hanging mass of entire moving system: from the the glider and all the metal string weights on the glider and string Pivot HANGING MASS SYSTEM MASS 80 + 0.1 g 700 + 0.1 g Change Our goal is to compare the theoretical results to actual results for this device. In this part, you'll calculate the predicted acceleration without seeing the video. In part two you'll see the video and compare your results to the video version. 1. If the system mass is 400 grams and the mass of the disks hanging on the string is 100 grams, what is the mass of the glider in your trial? 300 grams Submit Answer unlimited submissions remaining Comments: It is! 2. If the system mass is 400 grams and the mass of the disks hanging on the string is 100 grams, predict the acceleration. m/s/s Submit Answer X unlimited submissions remaining Heads Up!
