Force, Work how to determine force without accelration
I know we're not supposed to post up the full question but I figured it would just be easier to explain it. A 350 kg piano slides 3.8 m down a 31 degrees incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.30.
And I'm trying to figure out the force exerted by the man. Now what I got is F = m * a... so 350 kg is the mass and I guess gravity 9.8. So the force is 3234 N... but is that right? I just need to be led in the right direction.
