## Homework Statement

The pulleys in the figure (attached) are massless and frictionless, determine the acceleration of eah of m1 and m2, given that m1=4.00 kg, and m2=1.00 kg, and the surface is frictionless and horizontal.

## Homework Equations

For mass m1: T1=m1a1 and mass m2: w2-T2=m2a2

For the pulley 2T1=T2

## The Attempt at a Solution

I don’t understand how the mass m2, which is hanging, is moving. Why is it moving downwards? If m1 is moving to the right, then shouldn’t the pulley move anticlockwise and pull m2 upwards?

How is it attached?

How is the pulley making it move upwards or downwards if it’s attached to the center of the pulley?

How is the acceleration of a1=2a2?

Thank you
