Question
A car starts from rest and uniformly accelerates to a final speed of 20.0 m/s in a time of 15.0 s. How far does the car travel during this time?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Average speed = (0 + 20)/2 = 10 m/s. Distance = average speed × time = 10 × 15 = 150 m.
Hint
For constant acceleration, distance = average velocity × time.
