So, I have an atwood machine lab. What I have been given is the masses of either end and time it takes the heavier mass to hit the ground from a distance.
M1= .2kg
M2 = .15kg
avg time = 1.12 sec
What i think I have to do: To find the actual acceleration I have to use v = vi + at and solve for acceleration.
To find theoretical acceleration, I have to use a = ( (M2-M1) (g) )/ (M1+M2).
Theoretical: 1.4m/s/s
Actual: .697m/s/s
Kindly tell me if I am doing this right or not and how should I go about doing it correctly. It seems like these values I've obtained are incorrect and I'm missing something considering I didn't go into the topic we are studying very much. No use of free body diagrams or even sum of forces.
Thanks.
