Calculate the momentum of a toy car of mass 200 g moving with a speed of 5 m/s.

Academic Physics NCERT Class 9

Here given, mass of the toy $=200\ gm=\frac{200}{1000}\ kg=0.2\ kg$

Speed of the toy $v=5\ m/s$

Therefore, the momentum of the toy $P=mv$

$=0.2\ kg\times5\ m/s$

$=1\ kg-m/s$

Therefore, the momentum of the toy is $1\ kg-m/s$.
