Four rugby players are practicing the scrum and are locked shoulder-to-shoulder in a circle (see photo in lab lecture notes). They begin at rest then start pushing. Nate pushes with a force of 1200 N directly east. Doug pushes with a force of 1150 N southeast (45 above the left horizontal). Andrew pushes with a force of 2225 N southwest (35 above the right horizontal). Zach pushes with a force of 2195 N northwest (60 below the right horizontal).(a) What is the magnitude and direction of the resultant force? (b) What is the direction of the acceleration?
