Question

A 75 kg box slides down a 25 degree ramp with an acceleration of 3.60 meters per second squared. Find the coefficient of kenetic friction between the box and the ramp. What acceleration would a 175 kg box have on this ramp?
I have the first part of the question (0.061). I need the second part.

forcenetdown= mass*a
mgSinTheta-mu*mg*cosTheta=mass*a

but notice mass divides out, so acceleration is independent of mass, if it is moving.
yes
