Question
The maximum acceleration of the car is 20 m/s2.Calculate the time taken for the speed of the car to change from 0 m/s to 28 m/s at itsmaximum acceleration.[3 marks]Time taken = sQuestion 1 continues on the next page
Solution
The time taken for the speed of the car to change from 0 m/s to 28 m/s can be calculated using the formula:
Time = Change in speed / Acceleration
Given: Change in speed = 28 m/s - 0 m/s = 28 m/s Acceleration = 20 m/s²
Substituting the given values into the formula:
Time = 28 m/s / 20 m/s² = 1.4 seconds
So, it will take 1.4 seconds for the speed of the car to change from 0 m/s to 28 m/s at its maximum acceleration.
