The problem reads: "someone is pulling a 200kg sleigh across a field at a constant velocity. If the coefficient of kinetic friction is .13, how much work do they do on the sleigh if they pull it 94 meters?" I know I have to find force net and then use the formula for work (force x distance) how would I go about finding force net? Force friction+Force normalizing (which would be mass x gravity?) any guidance would be helpful asap. thanks!
