The 1st block has a mass of 10kg and the 2nd block has a mass of 20kg..

I need to find the acceleration in the string when a 50 N force is applied to the 2nd block...

I was thinking to find the acceleration I would do 50 N = (30kg)a

a = 1.6 but according to another problem that I looked at the acceleration would be 5.0 so now I'm confused for the correct way to find it.
