NEET 2014 Physics Impulse and Momentum MCQ Question
The force F acting on a particle of mass m is indicated by the force-time graph shown below. The change in momentum of the particle over the time interval from zero to 8 s is
24 Ns
20 Ns
12 Ns
6 Ns
Correct Answer
Detailed Explanation
The change in momentum is the area under the force-time graph. The area is a trapezoid with a base of 8 s and heights of 3 N and −3 N, giving a total area of 24 Ns.
