Answer:
acceleration = 16 m/s²
Step-by-step explanation:
According to Newton's second law of motion, acceleration of an object is directly proportional to the net force acting on it keeping the mass of the object constant.
Mathematically,
F ∝ a
It means that When there is no net force acting on the body, there is no acceleration. A force is a push or a pull, and the net force ΣF is the total force, or sum of the forces exerted on an object in all directions. When the net force is increased or decreased by a factor of X, then acceleration also increased or decreased by a factor of X respectively according to Newton's 2nd law of motion. In our case, net force increased by a factor of 2, So acceleration must also increased by a factor of 2.
F = ma
F = 8m N
2F = 16m N
So,
acceleration = 16 m/s²
