Two dogs, Ajax and Bandit, are pulling a Radio Flyer wagon carrying their best cat friend, Casper. the overhead view of the dog force vectors is shown to scale in the grid at the right. (Assume 4 significant figures.) a. Find the single force that is equivalent to the two forces shown. b. If that old rusty wagon DOES NOT MOVE, find the force (including direction) that the ground exerts on the wagon to keep it in place, in spite of the dogs. The forces are measured in units of newtons (N). (You may use EITHER geometry OR vector addition with Cartesian or polar coordinates. Either way, a diagram to scale is required. Be sure to JUSTIFY why your answer to part b is the opposite of your answer to part a.)
