With a total force of 20,000 newtons, an airplane has a mass of 1,200 kg. What is its acceleration?
swat32

Answer:

<h3>The answer is 16.67 m/s²</h3>

Explanation:

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

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

m =  \frac{20000}{1200}  =  \frac{200}{12}  \\  = 16.66666...

We have the final answer as

<h3>16.67 m/s²</h3>

Hope this helps you

<h3>What is Intuition?</h3>

This is the process in which individuals acquire knowledge without conscious reasoning(thoughts) about it.

In Khalil's case, he scored a low mark in it which means he will most likely score a high mark in what we refer to as counterintuition which is the opposite.
