I am really stuck on a few questions but i'll only post one. An adult is pulling two small children in a sleigh over level snow. The sleigh and children have a total mass of 47 kg. The sleigh rope makes an angle of 23 degrees with the horizontal. The coefficient of kinetic friction betwen the sleigh and the snow is 0.11. Calculate the magnitude of the tension in the rope needed to keep the sleigh moving at a constant velocity. (Hint. The normal force is not equal to the force of gravity.) I don't know what to figure out first. See i need Fn but i can't figure it out. I think Fn=Fg - Fapp(in the y direction). But i dont have a force to help me out. So can anyone please help me.
