Answer on Algebra Question for brittany

Question #24515
The formula for final velocity of an object starting from zero and undergoing constant acceleration is v=1/2at^2, what is the final velocity if a car is accelerating at 4 m/s^2 for 5 seconds
Expert's answer
This formula for distance:
s=1/2at^2
s - distance
a - acceleration
t - time
The formula for final velocity of an object starting from zero and undergoing constant acceleration is:
v=a*t
In our case:
a=4 m/s^2,
t= 5 sec,
Therefore:
v =a*t = 4m/s^2 * 5s = 20 m/sec = 20 m/sec &
