a car accelerates from 10 m/s to 30 m/s as the traffic break up on the highway. the acceleration occurs over 3.5 seconds of time. determine the acceleration of the car.

Given:

Initial velocity (u) = 10 m/s

Final velocity (v) = 30 m/s

Time taken (t) = 3.5 seconds

To Find:

Acceleration (a) of the car

Explanation:

From equation of motion:

Substituting value of v, u & t in the equation:

Acceleration (a) of the car = 5.7 m/s²
