Question

How to calculate that ​

Answer 1

Explanation:

Acceleration= 15-3/2

=6m/s²

Answer 2

Answer:

acceleration = $\bf 6 m/s^2$

Explanation:

We can calculate the acceleration of an object using the following formula:

$\boxed{acceleration = \frac{Resulatant \space\ force}{Mass}}$.

The resultant force is the effective force that is being applied to an object. In this case, there is a 15N force to the right, and a 3N force to the left.

∴ Resultant force = 15N - 3N

                             = 12N

Now we can use the formula for above formula to calculate acceleration:

$acceleration = \frac{12}{2}$

                    = $\bf 6 m/s^2$
