I calculate $3.2 m {s}^{-} 2$

#### Explanation:

In this situation we have a $15 k g$ object with a constant force of $48 N$ being applied to it. We can use Newton's Second Law, $F = m a$, to solve this problem.

We're trying to find the acceleration $a$, so first we must rearrange the equation to make $a$ the subject. This is done by dividing both sides by $m$ to give us:

$a = \frac{F}{m}$

Now we just substitute in the numbers and do the division!

$a = \frac{48}{15}$
$a = 3.2 m {s}^{-} 2$

Because the force applied is constant, this acceleration is also constant in size.
