Answer 1

Answer:

Step-by-step explanation:

P=mv                                                                                                                                        v=P/m                   v=200/40                                                                                                                                                           v=5ms^-1

Answer 2

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

• The velocity of the body = 5 m/s

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• A body of mass 40 kg has a momentum of 200 kg m/s.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

• The velocity of the body = ?

$\bf{\underline{\underline \blue{Explanation:-}}}$

$\sf\underline{\red{\:\:\: Formula\: Used\: Here:-\:\:\:}}$

$\bigstar \: \boxed{ \sf \: Momentum = \frac{Mass}{Velocity } }$

$\sf\underline{\green{\:\:\: Now,Putting\:the\: values:-\:\:\:}}$

$\dashrightarrow \sf {200 = 40 \times Velocity\:of \:the\:body}$

$\dashrightarrow \sf {Velocity \:of \:the\:body = \dfrac{\cancel{200}}{\cancel{40}} }$

$\dashrightarrow \sf {Velocity \:of \:the\:body = \dfrac{\cancel{20}}{\cancel{4}} }$

$\dashrightarrow \sf {Velocity\:of \:the\:body = 5\:m/s}$

$\sf\underline{\green{\:\:\: ThereFore:-\:\:\:}}$

• The velocity of the body is 5 m/s.

$\rule{200}{2}$
