three blocks are on a frictionless table. block a has a mass of 12kg, block b has a mass of 6kg, and block c has a mass of 8kg. a hand pushes left most box A such that the three boxes move in the positive horizontal direction at a rate of 2.2m/s^2
a) what is the magnitude of block a from the hand?
b)what is the net horizontal force on block a?
c) what is the horizontal force on block a due to block b?
d)what is the net horizontal force on block b?
e)what is the horizontal force of block b due to block c?
