NEET Physics Uniform & Non-uniform Motion MCQ Question
A car accelerates uniformly from rest along a straight road. After 4 seconds, its velocity reaches 20 m/s. What is the total displacement of the car during this time interval?
40 m
20 m
80 m
10 m
Correct Answer
Detailed Explanation
The car's acceleration can be calculated as (20 m/s - 0 m/s) / 4 s = 5 m/s². Using the kinematic equation for uniformly accelerated motion, displacement s = ut + (1/2)at², where u = 0, a = 5 m/s², and t = 4 s, gives s = 0 + (1/2)(5)(16) = 40 m.
