Question

The mass of a cannon is 500 kg and it recoils with a speed of
0.25 m/s. What is the momentum of the cannon ?​

Answer 1

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

Mass of the cannon = 500 kg

recoil speed of cannon = 0.25 m/s

$\underline{ \red{To \: find:}}$

Momentum = ?

$\underline{\red{ Formula:}}$

Momentum = mass(m) × velocity(v)

$\underline{\red{ Solution:}}$

$∴ \: Momentum = m \times v\: \: \: \: \: \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 500 \times 0.25 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =\green {\boxed{ 125 \: kg \: m/s}}$

∴ The momentum of the cannon is 125 kg m/s.

Answer 2

Answer:

Given:

Mass of the cannon = 500 kg

recoil speed of cannon = 0.25 m/s

\underline{ \red{To \: find:}}

Tofind:

Momentum = ?

\underline{\red{ Formula:}}

Formula:

Momentum = mass(m) × velocity(v)

\underline{\red{ Solution:}}

Solution:

\begin{gathered}∴ \: Momentum = m \times v\: \: \: \: \: \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 500 \times 0.25 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =\green {\boxed{ 125 \: kg \: m/s}}\end{gathered}

∴Momentum=m×v

=500×0.25

=

125kgm/s

∴ The momentum of the cannon is 125 kg m/s.
