Atwood's Machine Alex Chen Aim and task: 2(m1+m2)h = (MA+B)t^2 Assuming that (m1 + m2) is constant, plot a graph from which the value of the constants A and B can be deduced. And find out what the values should be. Method: Set up a pulley with 2 masses, m1 and m2 suspended on either side by a strong thread/string so that m2 is about 1.5m off the ground when m1 is resting on it. With m2 = 280g and m1 = 250g, obtain an accurate time for m2 to travel from rest through the distance 'h' to the ground. To do this, hold on mass m2 and ready to time, let m2 fall freely, and start the timer the same time. Stop the timer when it hits the ground (book). It will produce a loud noise when it hit the book. Repeat this five times to get an accurate result. Repeat the same...
