Problem
Two blocks of masses m1=2.0kg and m2=3.0kg are connected by a rigid, lightweight rod so that the distance between their centers remains constant. They rest on a horizontal, frictionless surface. A constant horizontal force of magnitude F=10N is applied to block m1 only, directed along the line joining the blocks, for a time interval of Δt=2.0s.
(a) Determine the magnitude of the acceleration of the system’s center of mass while the force is applied.
(b) Calculate the displacement of the center of mass during the 2.0 s interval.
(c) For the same interval, determine the magnitude of the acceleration of each individual block and explain why they have that value.
