I calculate 3.2 ms^-2

Explanation:

In this situation we have a 15 kg object with a constant force of 48 N being applied to it. We can use Newton's Second Law, F=ma, 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=F/m

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

a=48/15
a=3.2ms^-2

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