This is the most important question. please dont just take the pts

a = 0.6259 m/s²

Explanation:

This is similar to previous questions, the only difference is the mph, miles per hour. Since all of the previous questions are in m/s, I would assume the same here, so you have to convert mph to m/s.

1 mile = 1609.34m

1 hour = 3600s

So 0 mph = 0 m/s

and 14 mph = 6.259 m/s (you can see the image below to see how to do unit conversion)

a = average acceleration

v = final velocity = 6.259 m/s

v0 = initial velocity = 0 m/s

t = time = 10 s

a = (v-v0)/t

a = (6.259m/s - 0m/s) / 10s

a = 0.6259 m/s²
