The velocity of a body of mass 10 kg increases from 4 m/s to 8 m/s when a force acts on it for 2 s. What is the momentum after the force acts?

Academic Physics NCERT Class 9

Here, the mass of the body $m=10\ kg$

Initial velocity $u=4\ m/s$

Final velocity $v=8\ m/s$

The final momentum after the force acts $=mv=10\ kg\times8\ m/s$

$=80\ kg-m/s$
