# If an object is moving at 3 m/s and accelerates to 19 m/s over 2 seconds, what was the object's rate of acceleration?

Apr 9, 2018

it is $8 \frac{m}{s} ^ 2$.

#### Explanation:

we can use the following formula for calculating the acceleration...

$a = \frac{v - u}{t}$

so...

$a = \frac{19 - 3}{2}$

which is equal to...

$8 \frac{m}{s} ^ 2$ {in SI units}
