DYNAMICS OF RIGID BODIES

1. FINAL ANSWER MUST BE IN 3 DECIMAL PLACES
2. GIVE ILLUSTRATION AND LABEL THEM ACCORDINGLY

Two bodies A and B, weighing 400 lbs and 300 lbs, respectively, are connected by a rigid bar, 10 ft long and of negligible weight and move along the smooth surfaces. If they start from rest at the given position, determine the acceleration of B at this instant
