Micah knows that a car had a change in velocity of 15 m/s. What does Micah need to determine acceleration.

Question

distance
time
direction
speed

Answer 1

To determine acceleration, Micah needs to know time.

Acceleration is defined as the change in velocity divided by the time over which that change occurs. The formula for acceleration (a) is:

\[ a = \frac{\Delta v}{\Delta t} \]

where \( \Delta v \) is the change in velocity (in this case 15 m/s) and \( \Delta t \) is the time taken for that change.
