Lillian walks her dog every afternoon after school. Today, her dog was not wanting to go down the street that Lillian wanted to walk down. The dog then began pulling on the leash one way, and Jillian pulled on the leash in the opposite direction. If the dog is pulling the leash at 60 N one way, at what force should Jillian pull on the leash in that same direction to obtain and maintain static equilibrium?
