Question
I asked you yesterday this questions and you solved it like this!!!! Where did you get the distance from???? You used 10 for distance…. I did not give you a distance in the question??? A 5 kg block is moved up a 30 degree incline by a force of 50 N, parallel to the incline. The coefficient of kinetic friction between the block and the incline is 0.25. What is the net work done on the block over this distance?
