## Homework Statement

From an inertial reference frame S, the vector position of a particle of mass

m1 = 1kg is given by r1(t)=(tx-hat - t^2y-hat)m.

The vector position of a particle m2=2m1 is given by r2=(t)=(tx-hat +t^3y-hat)m

Is particle #1 free along the y-direction? Explain

## Homework Equations

If the particle is free along the y-direction then the y's would equal to 0.

## The Attempt at a Solution

r1= -t^2y

r2=+t^3y

=not free?

(I am actually unsure if my definition of free is true)
