What is the acceleration of a cabinet of mass 45 kilograms if Jake and Ted push it by applying horizontal force of 25 newtons and 18 newtons respectively in the same direction? (Assume a flat, frictionless surface.)
Since force is a vector quantity and they acting in the same direction, net force(F) = 25 + 18 = 43N. According to Newton's 2nd law of motion, F = mass x acceleration. acceleration = F/m= 43/45 = 0.95 m/s2.
