Answer:
8 m/s²
Explanation:
There are many formulas that can be used to calculate acceleration, time, initial velocity, final velocity and distance.
One such formula is:
v = u + at (v = final velocity; u = initial velocity; a = acceleration; t = time)
Using the values given in the question, all we need to do is rearrange the formula to make a the subject of the formula:
a = (v - u) / t
a = (40 m/s - 0 m/s) / (5 s)
a = (40 m/s) / (5 s)
a = 8 m/s²
