28 m/s is the velocity , when it is going after 4.0 seconds.
When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.
Here, given that,
A car is moving at a constant acceleration of 7.0 m/s/s
Now, we have,
Velocity = acceleration * time
After 4 sec. = 7*4 = 28 m/s
Hence, 28 m/s is the velocity , when it is going after 4.0 seconds.
