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

Acceleration is defined as the rate of change of velocity per unit of time. In other words, it's how much the velocity (speed in a given direction) changes over a certain period of time. In this case, Micah already knows the change in velocity, which is 15 m/s. To calculate acceleration, he needs to know the time over which this change occurred. The formula for acceleration is: where:- is acceleration,- is the change in velocity, and- is the time over which the change occurred.So, Micah needs to know the time to determine acceleration.
