I assume the object starts from rest. The speed will be 16*3 which is 48m/s
-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.
The acceleration of the object is the rate at which its velocity changes over time, measured in meters per second squared.
2 miles per second squared
-2.33 metres per second squared
Speed, or velocity, is measured in distance per second; it is the rate of change of distance with time.Acceleration is the rate of change of velocity with time, or distance per second per second, which is distance per seconds 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.
It is metres per second per second or metres per second squared.
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.
10 feet per second squared
The answer is B - 3 meters per second squared
