An overnight rainstorm has caused a major roadblock. three massive rocks of mass m1=598kg, m2=796kg and m3=311kg have blocked a busy road. the city calls a local contractor to use a bulldozer to clear the road. the bulldozer applies a constant force to m1 to slide the rocks off the road. assuming the road is a flat frictionless surface and the rocks are all in contact, what force, fa must be applied to m1 to slowly accelerate the group of rocks from the road at 0.100m/s2. use the value found above fro fa to find the force f12 exerted by the first rock of mass 598kg on the middle rock of 769kg
