Three masses are connected by a string.
M1 = 1.0kg
M2 = 2.0kg
M3 = 3.0kg
Mass one and two are on a table while mass three hangs off the edge of the table (there is a pulley). Find the tension in the string connecting m1 and m2. Assume the table is frictionless and the masses move freely. Find the tension in the string connecting m2 and m3.

1. force down on m3 = m3 * g = 29.4 N

F = m a

29.4 = (1+2+3) a

a = 29.4/6 m/s^2

tension between m1 and m2 = m1 a = 1 a

m3 g - Tension up on m3 = m3 a

tension between m1 and m2 = m1 a
