Answer:
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:
Acceleration
Explanation:
Acceleration is a physical quantity that expresses the change in the velocity of a body per unit of time.
Acceleration =
V is the initial velocity
U is the final velocity
T is the time
It is has a unit of m/s²
