A vehicle moving with a uniform a acceleration of 2m/s and has a velocity of 4m/s at a certain time . what is will its velocity be
a: 1s later
b: 5s later.

1 second later the vehicle's velocity will be:

5 seconds later the vehicle's velocity will be:

Explanation:

Recall the formula for the velocity of an object under constant accelerated motion (with acceleration ""):

Therefore, in this case  and

so we can estimate the velocity of the vehicle at different times just by replacing the requested "t" in the expression:

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.
