NEET Physics Uniform & Non-uniform Motion MCQ Question
Type: MCQ-numerical-Hard-Class 11
A car moves with a constant velocity of 15 m/s for 10 seconds, then comes to a rest with uniform deceleration in the next 5 seconds. What is the total displacement of the car?
A
150 m
B
225 m
C
300 m
D
375 m
Correct Answer
Option B
Detailed Explanation
The car travels 150 m during the first 10 seconds at constant velocity. It then decelerates uniformly to rest in 5 seconds, covering an additional 75 m (using the equation v^2 = u^2 + 2a(x - x0)). Thus, the total displacement is 225 m.
