What is the net force and acceleration of a ball of mass 0.750 kilograms that is subjected to forces of 11.00 newtons and 7.00 newtons from opposite directions?

since no axes/directions are given, let's just consider magnitudes for now

if the 11.0 and 7.0 are acting in opposite directions, the 7.0 in one direction cancels out the 7.0 in the opposite direction, so we're left with a net force of 11.0 - 7.0 = 4.0

plug 4.0 as F, and 0.750kg as m into the equation F = ma and solve for a
