## Problem

In the diagram below, Block 2 has twice the mass of Block 1. Assume that the pulley is frictionless and that both the rope and pulley are massless. Use g, equals, 9, point, 8, start fraction, start text, m, end text, divided by, start text, s, end text, squared, end fraction.
Two masses are connected by a string and pulley. Mass one is represented by a box hanging from the left side of the pulley. Mass two is represented by a larger box hanging from the right side of the pulley. Mass two hangs farther down than mass one.
Calculate the magnitude of acceleration of the blocks.
Write your answer using two significant figures.
