It seems to be an easy question but for some reason I can't figure it out.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

If the 10 lb block A slides down the plane with a constant velocity when θ = 30°, determine the acceleration of the block when θ = 45°.

2. Relevant equations

F = ma

3. The attempt at a solution

I actually am very puzzled by this question. I know that acceleration = 0 at 30° but I don't know how to make use of it. I tried setting the parallel force at 45° to equal ma, then solve for a, but that didn't do it either. Any insight? Thanks.
