A child on a sled (having a combined mass of 47.0 kg) is pulled by a force directed along a rope that makes a 45 degree angle with the horizontal axis. the force exerted on the rope is 100.00 N. the force of friction acting on the sled is 30.0 N. if the child is pulled a distance of 10.0 m along a level field, determine the total work done on the child and the sled. Attempt: Given: d: 10.0 m, F:100.0 N (45 degrees), Ff: 30.0 N (180 Degrees) W=F(costheta) . deltad W= 100.00 N X cos45 X 10.0m W=707J that would be just for the rope would i have to do the same calculation using the Ff now? then add both numbers to get total work done? It also asks for the final speed at the end of 10.0 m HELP PLEASE!
