Two objects are connected by a very light flexible string as shown in the figure, where M = 0.60 kg and m = 0.40 kg. You can ignore friction and the mass of the pulley.
 
  (a) Draw free-body diagrams for each object.
  (b) Calculate the magnitude of the acceleration of each object.
  (c) Calculate the tension in the string.
  What will be an ideal response?

Question 2

A wooden block A of mass 4.0 kg slides on a frictionless table when pulled using a massless string and pulley array by a hanging box B of mass 5.0 kg, as shown in the figure.
 
  What is the acceleration of block A as it slides on the frictionless table? Hint: Think carefully about the acceleration constraint.
 
  A) 4.1 m/s2
  B) 3.5 m/s2
  C) 3.1 m/s2
  D) 2.7 m/s2
