-2.33 metres per second squared
IF it started out from rest, then V = a t = (7.8 x 30) = 234 meters per secondin the direction of the acceleration, at the end of 30 seconds.
-6.667 miles per second squared
Acceleration is measured in m/s2 (metres per second squared)
The sprinter's acceleration is 2 meters per second squared.
Seconds are not squared in the acceleration formula. The units for acceleration are meters per second squared (m/s^2), where the time unit (seconds) is squared to represent the change in velocity over time.
2 miles per second squared
-2.33 metres per second squared
Acceleration measures the rate of change of velocity over time. The squared seconds unit is used because acceleration is the change in velocity per unit time, so it is expressed as distance per time squared. This allows us to quantify how quickly the velocity of an object is changing over time.
IF it started out from rest, then V = a t = (7.8 x 30) = 234 meters per secondin the direction of the acceleration, at the end of 30 seconds.
The SI unit for acceleration is meters per second squared (m/s^2). This unit represents how the velocity of an object changes over time.
Acceleration of the object.
Velocity can be measured in metres per second, not metres per second squared. Acceleration is measured in metres per second squared but knowing only the acceleration does not help in finding the velocity.
We use meters per second squared to measure acceleration because it represents the rate at which an object's velocity is changing over time. It signifies how quickly the speed of an object is increasing or decreasing relative to time.
