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.

  • Physics -

    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
