In 1991 four english teenagers built an eletric car that could attain a speed of 30.0m/s. suppose it takes 8.0s for this car to accelerate from 18.0m/s to 30.0m/s. what is the magnitude of the car's acceleration?

Acceleration of the car,

Explanation:

It is given that,

Initial speed of the car, u = 18 m/s

Final speed of the car, v = 30 m/s

Time taken, t = 8 s

We need to find the acceleration of the car. Let it is given by a. It can be calculated using the first equation of motion.

Where

a is the acceleration of the car.

So, the magnitude of the car's acceleration is . Hence, this is the required solution.
