Question

The mass of the cannon is 700 kg and it recoils with a speed of 0.35 m/s.What is the momentum of the cannon?

Answer 1

Answer:

245kg m/s

Explanation:

mass of the canon= 700kg

recoil speed = 0.35m/s

momentum=?

momentum = m×v

momentum = 700× 0.35

momentum=245 kg m/s

therefore, the momentum of the canon is 245 kg m/s.

hope it will help you all..

thanks

Answer 2

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

Mass of the cannon = 700 kg

recoil speed of cannon = 0.35 m/s

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

Momentum = ?

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

Momentum = mass(m) × velocity(v)

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

$∴ \: Momentum = m \times v\: \: \: \: \: \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 700 \times 0.35 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =\green {\boxed{ 245\: kg \: m/s}}$

∴ The momentum of the cannon is 245 kg m/s.
