Homework Statement
One mass, m1 = 215g, of an ideal Atwood machine rests on the floor 1.10m below the other mass, m2 = 255g. (a) If the masses are released from rest, how long does it take m2 to reach the floor? (b) How high will mass m1 ascend from the floor?
Known variables:
m1 = 215g = 0.215kg = F1
m2 = 255g = 0.255kg = F2
yd = 1.10m
Homework Equations
F2 - F1 = (m1 + m2)a
yd = v0t + 1/2at2
The Attempt at a Solution
A.
2.5N - 2.1N = (0.255kg + 0.215kg)*a
0.4N = 0.47kg*a
a = 0.851m/s2
1.10m = 1/2*(0.851m/s2)*t2
t = 1.61s
B. I think I have to use equation 'b' in the relevant equations section but I do not know how to use it properly. For this part I have the masses or each object, the acceleration of the entire apparatus, and the different forces. Any insight on this problem would be greatly appreciated!
