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 inerval from zero to 8 s is

Moderate

A

24N s
B

20N s
C

12N s
D

6N s

Solution

Change in momentum = Area under F-t graph $\frac{1}{2} (2 \times 6) - (2 \times 3) + 4 \times 3 = 12 N s$
