(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Object weighing 100 grams is on a surface which is inclined to an angle where the mass just overcame the coefficient of friction (which is unknown) and started sliding down. Angle was measured to be 21 degrees to the horizontal.

What I want to know is would the mass have a constant velocity, thus acceleration of 0?

Why?

Also is this right in resolving the problem into x and y components:

x-component = mgsintheta - mumgcostheta (where mu = coefficient of friction)

y-component = None, as the object does not move in directions perpendicular to the plane.

Would greatly appreciate help, stressed out and struggling all day...
