AIPMT MAINS 2009 Physics Kinematics MCQ Question

Type: MCQ-conceptual-Medium-Class 11

A particle starts its motion from rest under the action of a constant force. If the distance covered in first 10 seconds is S₁ and that covered in the first 20 seconds is S₂, then:

A

S₂ = 3S₁

B

S₂ = 4S₁

C

S₂ = S₁

D

S₂ = 2S₁

Correct Answer

Option D

Detailed Explanation

The distance covered under constant acceleration is proportional to the square of the time. Therefore, S₂/S₁ = (20/10)² = 4.
