Question

If the velocity changes from 10 m/s to 12 m/s in one second, what is the acceleration?

Answer 1

`2 ms^-2`

Explanation:

Considering the known variables, we have the initial velocity (u), the final velocity (v) and the time (t). We can now use the formula `v = u+at` to determine the acceleration.
Substituting, we get: `12 = 10 + a`. We can now solve for `a`.
`12-10=a`
Therefore `2 =a`.
