during a journey a car accelerate from 9m per second to 18m per second in 6 seconds .calculate the acceleration of the car
Question
During a journey a car accelerates from 9 m/s to 18 m/s in 6 seconds.
Calculate the acceleration of the car.
Solution
The acceleration of an object is calculated by the formula:
Acceleration = (Final velocity - Initial velocity) / Time
In this case, the final velocity (v_f) is 18 m/s, the initial velocity (v_i) is 9 m/s, and the time (t) is 6 seconds.
So, the acceleration (a) would be:
a = (v_f - v_i) / t a = (18 m/s - 9 m/s) / 6 s a = 9 m/s / 6 s a = 1.5 m/s²
So, the acceleration of the car is 1.5 meters per second squared.
