2. When I walk my dog, he is often very stubborn and does not want to go in the same direction I do. When this happens he likes to pull back against his leash so he doesn’t go anywhere. (Don’t worry, it’s attached to a chest harness, not to his neck). I was curious, so one day I attached a force sensor to his leash and found that I try to pull him with a force of 22.0 N at an angle of 25.0°, like in the figure below. We can assume that the coefficients of friction between my dog’s paws and the sidewalk are 0.500 for static friction and 0.300 for kinetic friction.
Assume the dog is moving to the right at a constant velocity.
