Explanation:
It is given that,
Initial velocity of the car, u = 14 m/s
Final velocity of the car, v = 21 m/s
Time taken, t = 6 s
Acceleration of the car is equal to the change in speed divided by time i.e. it can be written as :
a = 1.166 m/s²
or
a = 1.17 m/s²
For finding how fat it travel in this time is calculated using third equation of motion :
s = distance
s = 104.7 m
Hence, the acceleration of the car is 1.166 m/s² and distance covered by it is 104.7 m
