## Homework Statement

Masses of 350g and 175g are attached by a light string and hanging straight down from a light frictionless pulley. The 350g mass is 1.5m above the ground. What speed will the system have when the 350g mass hits the ground.

My attempt at a data list is (after i drew a diagram)

mA=350g

mB=175g

vA1=0m/s

vA2=?

hA1=1.5m

hA2=0m

Assume Gravity is 9.8m/s [down]

## Homework Equations

Wnc=E2-E1

E2=E1

## The Attempt at a Solution

I can not figure out how to figure out this question as I am not sure how my formula should look to include both masses in the situation.
