Question

A car of mass 10kg is moving with a velocity of 72km/h. Find its momentum​

Answer 1

Solution :-

Given :-

• Mass (m) → 10 kg
• Velocity (v) → 72 km/hr = 20 m/s

To Find :-

• Momentum (p)

Formula Used :-

• $\underline{ \boxed{ \pink{ \sf Momentum (p) = Mass (m) \times Velocity (v) }}}$

Substituting Values

$\implies \sf p = 10 . kg\times 20 . m \: {s}^{ - 1}$

$\implies \sf p = 10 \times 20 . kg . m \: {s}^{ - 1}$

$\implies \sf p = 200 . kg . m \: {s}^{ - 1}$

$\implies \sf p = 200 \: kg \: m \: {s}^{ - 1}$

Thus, the momentum is 200 kg m/s

Hence, Solved ♡

Answer 2

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

$\pink\bigstar\;\underline{\textbf{\textsf{AnswEr:-}}}$

• The required momentum = 200 kg m/s

$\pink\bigstar\;\underline{\textbf{\textsf{Given:-}}}$

• A car of mass 10kg is moving with a velocity of 72km/h.

$\pink\bigstar\;\underline{\textbf{\textsf{Need to find:-}}}$

• The required momentum = ?

$\:\:\:\:\;\:\;\footnotesize\bold{\underline{\underline{\sf{\red{Step\:by\:step\: Explanation:-}}}}}$

$\star \sf {Velocity = 72 km/hour}$

$\star \sf {Velocity = 20 m/s}$

$\bullet\;\;\underline{\textbf{\textsf{Formula used here:-}}}$

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

$\bullet\;\;\underline{\textbf{\textsf{Putting the values:-}}}$

$\longrightarrow \sf {Required\:Momentum = 10\:kg \times 20\:ms{^-} {^1}}$

$\longrightarrow \sf {Required\:Momentum = 10 \times 20\:kg.ms{^-}{^1}}$

$\longrightarrow \sf {Required\:Momentum = 200\:kg.ms{^-}{^1}}$

$\bullet\;\;\underline{\textbf{\textsf{Therefore:-}}}$

• The required momentum is 200 kg m/s.
