What net force would be needed to accelerate the box at 2.3 m/s^2

In a simple electric circuit, ohm's law states that v=irv=ir, where vv is the voltage in volts, ii is the current in amperes, and rr is the resistance in ohms. assume that, as the battery wears out, the voltage decreases at 0.030.

How do you best determine whether j/m2 and m*s2/n are equivalent units?
