Three blocks, each of mass 14.0 kg are on a frictionless table. A hand pushes on the left most box (A) such that the three boxes accelerate in the positive horizontal direction as shown at a rate of a = 0.5 m/s2.
1) What is the magnitude of the force on block A from the hand?
2) What is the net horizontal force on block A ?
3) What is the horizontal force on block A due to block B?
