What is the net force needed to accelerate a 1 kg textbook with an acceleration of
4 m/s2

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question

mass = 1 kg

acceleration = 4 m/s²

We have

force = 1 × 4 = 4

We have the final answer as
