Two sled dogs are pulling on the same sled. The sled needs to travel due North. The first dog, Chuck, is pulling with 135 pounds of force at an angle 15 degrees West of North. The second dog, Rufus, is young and exuberant, but is often a little confused. Rufus is trying to chase a rabbit, so he is pulling at an angle of 40 degrees East of South.How many pounds of force will Rufus need to pull with in order to keep the sled moving due North?
