If an object is pushed 5m along a certain incline, its height above the ground increases by 2m. If the incline were frictionless it would require a force of 196N exerted parallel to the incline to push a 50kg crate up the incline at a constant speed. How much work would be done in pushing the crate up the incline?

Best ResponseYou've already chosen the best response.1Work is equal to force times displacement times the cosine of the angle. W=f*s*cos(theta) The tricky part of your problem is finding theta. Since I'm on my phone I can't draw the picture as I would like to, but you are going to take the arctan of 5/2 to find the angle. Tan^1(5/2)=calculated angle. The rest of this problem is plug and chug. W=196N*5m*calculated angle

Best ResponseYou've already chosen the best response.1I'm sorry, I said arc tan and it should be arcsin because sin=opp/hyp. And work will be: W=196N*5m*cos(calculated angle) Sorry for the mistakes. All should be correct now
