# How fast will an object with a mass of #15 kg# accelerate if a force of # 72 N# is constantly applied to it?

##### 2 Answers

The acceleration is

#### Explanation:

The formula that describes the relationship discussed in Newton's 2nd Law is

To find acceleration when knowing force and mass, we need to do some algebra on the above formula. Divide both sides by m and cancel where possible.

So

If we plug your data into that equation and perform the indicated division, we find that

The usual units for acceleration are

But, if we look at

Therefore,

I hope this helps,

#### Explanation:

We use Newton's second law of motion here, which states that

where

We need to solve for acceleration, so we can rearrange the equation into

Now, plugging in the given values, we get

So, the object's velocity will keep increasing by
