Problem

Blocks of mass

4.0\,\text{kg}

and

6.0\,\text{kg}

are connected by a light string that passes over a frictionless pulley. The

6.0\,\text{kg}

block hangs freely, and the

4.0\,\text{kg}

block rests on a frictionless horizontal table. Starting from rest, what is the magnitude of the acceleration of the system? (Use

g = 9.8\,\text{m/s}^2

.) a)

9.8\,\text{m/s}^2

3.9\,\text{m/s}^2

5.9\,\text{m/s}^2

2.0\,\text{m/s}^2
