**Finding speed with a pulley?**

## Homework Statement

Two objects are connected by a light string

passing over a light frictionless pulley as

shown in the figure. The 5.9 kg object is

released from rest at a point 4.53 m above the

floor.

What is the speed of the each object at

the instant before the 5.9 kg hits the floor?

Answer in units of m/s.
