Homework Help: physics

Posted by mclanee on Wednesday, September 13, 2006 at 7:51pm.

A 2.0kg block is sitting on a 15 degree incline. The coefficient of friction is 0.22. What is the minimum force needed to cause the block to accelerate UP the slope?


The force applied has to be slightly greater than the force of friction (mu(mgCosTheta)) plus the component of weight down the slope (mgSinTheta).

I will be happy to critique your work.
