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:

  1. 24 Ns
  2. 20 Ns
  3. 12 Ns
  4. 6 Ns

Solution

As we know that:-

Area under force-time graph gives as momentum

∆P=ar of given curve

∆P=12×b×h + l1×b1 + l2×b2

∆P=1226-32+423
=6-6+12
=12
