A car traveling at 98 km/h comes to a stop in 15 s. What is the car's acceleration in km/h/s?
Answer:
Acceleration of the car is 6.53 km/h/s
Explanation:
It is given that,
Initial velocity of the car is, u = 98 km/h
Finally it is coming to rest so v = 0
Time taken to stop, t = 15 s
We have to find the acceleration of the car. It is given by the ratio of change in velocity and time taken.
\(a=\dfrac{dv}{dt}\)
\(a=\dfrac{98\ km/h-0}{15\ s}\)
a = 6.53 km/h/s
Hence, the acceleration of the car is 6.53 km/h/s
