Object of masses: mass1= 4.000 kg and mass2=9.000 kg, are connected by a light string that passes over a frictionless pulley. The object mass1 is held at rest on the floor, and mass2 is rest on an inclined of 40 degrees. The objects are released from rest and mass2 slides 1.000 meter in 4.000 seconds. Determine the acceleration of each object.
