Ryan is out walking 3 dogs on a single leash (like the one pictured right). One of the dogs pulls with a force of 150 N at a bearing of 60. Another dog pulls with a force of 200 N at a bearing of 150. The remaining dog pulls with a force of 280 N at a bearing of 200.

What is the resultant force of all three dogs pulling (including direction)?

b. With what force (and in which direction) will Ryan need to pull to ensure he can stay in place?
