Three blocks are in contact with one another on a frictionless, horizontal surface as in the figure below. A horizontal force F→ is applied to m1, where m1 = 1.90 kg, m2 = 3.73 kg, m3 = 4.92 kg, and F = 20.0 N. (Take the +x-direction to be to the right. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Find the acceleration of the blocks. (Enter your answer in m/s2. Indicate the direction with the sign of your answer.) m/s2 (b) Find the net force on each block. (Enter your answers in N.
