Question

Micah knows that a car had a change in velocity of 15 m/s. To determine acceleration, Micah also needs the_______________

Answer 1

Answer: Time

Explanation: Took the test and got it right! :)

Answer 2

Answer:

Duration of the total trip

Explanation:

Acceleration is defined as the rate of change of velocity of an object:

$a=\frac{\Delta v}{\Delta t}$

where

$\Delta v$ is the change in velocity

$\Delta t$ is the duration of the change in velocity

Acceleration is measured in meters per squared seconds, $m/s^2$. Also, we should note that acceleration is a vector quantity, so in order to completely define acceleration we also need to specify the direction.
