Question
The table below shows the speed of a car at different times. The acceleration of the car after 4 seconds after start is _______ m/s2.
Hint:
Acceleration = velocity/time
The correct answer is: 7
Acceleration is defined as change in velocity with change in time.
Here, the car starts from 0 and after 4 seconds it's velocity is 28m/s.
So, the acceleration will be
28/4 = 7 m/s² .
