Two Dogs and a Tire: A Physics Experiment

[RZA]

1. Two dogs, separate by 137 degree of arc, grab a tire and pull simultaneously. The first dog pulls with a force of 220N. The second dog pulls with a force of 230N. A third dog joins in on the fun and grabs the tire as well, pulling just enough to bring thee other 2 dogs and the tire to a standstill.

1. Relative to the pit bull, where is the 3rd dog?

2. With how much force is the 3rd dog pulling the tire?



2. F=MA

Not sure to be honest

Nevermind, got it.

Find the resultant of two forces 220 N and 230 N with an angle 137 degree with each other. That will be the pulling force of the third dog.
