Two sled dogs are pulling on the same sled, which 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 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?

Answer :

Step-by-step explanation:

The horizontal components must match or the sled will veer away from due north

See image below

135 sin 15 = Rufus sin 40

shows Rufus = 54.4 pounds of pulling force

if Rufus pulls a bit harder the sled will veer eastward

if Rufus pulls very much harder the sled will go east and SOUTH
