What is the acceleration of an object with mass 42.6kg when an unbalanced force of 112N is applied

2.63 m/s2

Explanation:

Using newton's second law of motion that describe the relationship between object mass and amount of force needed to accelerate it.

F=ma

F = force acting on the object

m = mass of object

a = acceleration

a = F/m

a = 112/42.6 = 2.63m/s2

a = 2.63m/s^2
