NEET Physics Uniform & Non-uniform Motion MCQ Question
Type: MCQ-numerical-Hard-Class 11
A car moves in a straight line with an initial velocity of 5 m/s and a uniform acceleration of 2 m/s². What is the displacement of the car after 4 seconds?
A
36 m
B
44 m
C
32 m
D
40 m
Correct Answer
Option B
Detailed Explanation
Using the equation for displacement with uniform acceleration: s = ut + 0.5at², where u = 5 m/s, a = 2 m/s², and t = 4 s. Therefore, s = 54 + 0.52*4² = 20 + 16 = 44 m.
