i really need help on this problem!! Three blocks are connected,on a horizontal frictionless table and pulled to the right with a force T3 = 64.4 N. Assume that m1 = 12.5 kg, m2 = 25.0 kg, and m3 = 31.7 kg. (a) Calculate the acceleration of the system (b)...

yes since you x value is positive the graph opens upwards, and all absolute value graphs have a distinct V shape, using the vertical line test you can see that it is a function
