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

• A. 24 Ns
• B. 20 Ns
• C. 12 Ns
• D. 6 Ns

Answer 1

The correct option is C 12 Ns

$\Delta P=\left(\frac{1}{2}\right)\left(2\right)\left(6\right)-\left(3\right)\left(2\right)+\left(4\right)\left(3\right)$
$=6-6+12$
$=12$
