Three blocks are in contact with each other on a frictionless,horizontal surface. A horizontal force F is applied toM1. M1= 2kg, M2=3kg, M3= 4kg, and F=18N. (M1,M2,M3 are allsitting side by side)
PART A) Find the resultant force on each block.
PART B) Find the magnitudes of the contact forcesbetween the blocks.
