Question

Bob needs to accelerate a 4 kg box at 2 m/s2. How much force does he need to use?

Answer 1

8 N

Step-by-step explanation:

From Newtons second law of motion, we have;

F = ma

where: F is the force applied, m is the mass of the object, and a is its acceleration.

From the given question: mass of box = 4 kg and acceleration of the box = 2 m/
`s^(2)`, then;

F = 4 x 2

= 8

F = 8 N

The amount of force to be used is 8 N.
