4 An Atwood's machine that has a frictionless massless pulley and mass- less strings has a 2.00[kg] object hanging from one side and 0.000004 [kiloton (kt)] object hanging from the other side. a) Draw the Free Body Diagram for this situation. b) What is the speed of each object 1.50 s after they are released from rest? c) At that time, what is the velocity of the center of mass of the two objects? d) At that time, what is the acceleration of the center of mass of the two objects?
