STANDARD Physics Impulse and Momentum MCQ Question

Type: MCQ-numerical-Medium-Class 11

The position-time graph of a body of mass 2 kg is as shown in figure. What is the impulse on the body at t = 4 s?

Question diagram
A

2/3 kg m s⁻¹

B

-2/3 kg m s⁻¹

C

3/2 kg m s⁻¹

D

-3/2 kg m s⁻¹

Correct Answer

Option D

Detailed Explanation

At t = 4 s, the body has constant velocity u = 3/4 m s⁻¹. After t = 4 s, the body is at rest i.e., v = 0. Impulse = m(v - u) = 2 kg (0 - 3/4 m s⁻¹) = -3/2 kg m s⁻¹.
