Question

if mass of body is 10kg moving with velocity 20m/s what is the momentum of body​

Answer 1

$\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}$

• Mass of body = 10 kg.

• Velocity of the body = 20 m/s.

$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}$

• Momentum of the body.

$\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}$

• Mass of the body = 10 kg.

• Velocity of the body = 20 m/s.

• Momentum = ?

• $\boxed{\pink{\sf Momentum \: = \: Mass \: * \: Velocity}}$

• Substituting the values,

• Momentum = 10 * 20

• $\underline{\boxed{\purple{\sf 200 \: kg.m/s}}}$

Answer 2

${\pmb{\sf{\underline{Solution...}}}}$

★ Momentum of the body = 200 kg.m/s

${\pmb{\sf{\underline{Understanding \; the \; Question...}}}}$

★ This question says that we have to find out the momentum of the body, if the mass of the body is given as 10 kilograms and it is moving with a velocity/speed of 20 metres per second.

${\pmb{\sf{\underline{Explaination...}}}}$

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Explaination \\ \\ \star \: \sf{Mass \: of \: the \: body \: = 10 \: kg} \\ \\ \star\sf \: {Body \: is \: moving \: with \: velocity \: = 20 \: m/s} \\ \\ \star \: \sf{Momentum \: of \: the \: body \: = \: ?} \end{array}}\end{gathered}$

${\pmb{\sf{\underline{Using \; Formula...}}}}$

★ Formula to find out the momentum of the body =

${\small{\underline{\boxed{\sf{Momentum \: = Mass \times Velocity}}}}}$

${\pmb{\sf{\underline{Full \; Solution...}}}}$

${\small{\underline{\boxed{\sf{Momentum \: = Mass \times Velocity}}}}} \\ \\ :\implies \sf Momentum \: = Mass \times Velocity \\ \\ :\implies \sf Momentum \: = 10 \times 20 \\ \\ :\implies \sf Momentum \: = 200 \: kg.m/s$

Momentum of the body is 200 kg.m/s

${\pmb{\sf{\underline{Knowledge...}}}}$

★ Momentum - It is that property of a moving body and is defined of mass and velocity of the body. It's a vector quantity. SI unit is kgm/s.
