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.
