Find the acceleration of the masses shown in Figure, given that m1 = 1.0 kg, m2 = 2.0 kg, and m3 = 3.0 kg. Assume the table is frictionless and the masses move freely.

Answer 1

Is m1, m2 on the horiontal table? And m3 hanging?

force pulling= m3*g
mass being moved= (m1+m2+m3)

Fpulling= masstotal * a solve for a.
