Calculate the momentum of a body of mass 100kg having K.E.of 20 joule

1.	Calculate the momentum of a body of mass 100kg having K.E.of 20 joule .
Answer» *given that ,* *m =100 g = 100/1000 kg* *K.E.=20 Joule* $\frac{1}{2} m<klux>V</klux>^2$ *K.E.=* $\frac{1}{2} * \frac{100}{1000} * v^2$ *20 J =* $20 2 10 = v^2$ $\sqrt{400} = v$ *THEREFORE, v = 20* $mv$ *momentum =* **= 100 20* = 2000 gm/s = 2 kgm/s**
