Explanation:
Initial velocity of a car is 10 m/s
The speed is up to 20 m/s in 5 seconds.
Initial velocity u = 10 m/s
Final velocity v = 20 m/s
Time t = 5 seconds.
We know that :
v = u + at
So , putting values in the equation
20 = 10 + a × 6
=> a × 6 = 10
=> a= 10 / 6
=> a= 1.66 m/s^2
Therefore , the acceleration of the car is 1.66 m/s^2
