Acar going at 30 m/s undergoes an acceleration of 2 m/s^2 for 4 seconds. what is it's final speed? how far did it travel while it was accelerating

Explanation:

It is given that,

Initial velocity of the car, u = 30 m/s

Acceleration of the car, a = 2 m/s²

Time taken, t = 4 seconds

(1) We need to find the final velocity of the car. It can be calculated using first equation of motion as :

v = 38 m/s

The final speed of the car is 38 m/s.

(2) Let s is the distance travelled by the car. Using third equation of motion as :

s = 136 meters

So, while accelerating it will travel 136 meters. Hence, this is the required solution.
