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
Options
A.24 Ns
B.20 Ns
C.12 Ns
D.6 Ns
Solution
Change in momentum = Area below the F versus t graph in that interval
=
- (2 × 3) + (4 × 3)
= 6 - 6 + 12 = Ns
=
- (2 × 3) + (4 × 3)= 6 - 6 + 12 = Ns
