Question

Calculate the momentum of object of mass 5kg e moving at a speed of 20 km per hour

Answer 1

$\tt{\huge{\pink{Hello!!! }}}$

Momentum refers to the quantity of motion of an object.

It is

$\tt{ \purple{ \implies{ \vec{p} \: = m \: \times \vec{v} }}}$

Placing the values and equating we get :

$\tt{ \orange{ \implies{ \vec{p} =27.77 \: km.{m}^{-1}.{s}^{-1} }}}$

Answer 2

Answer:

Given:

Mass of object = 5 kg

Speed of object = 20 km/hr

To find:

Momentum of the object

Concept:

Momentum is actually an index of Inertia of Motion of a particle. In other words , it's the product of mass and velocity of the Object.It's an vector QuantityIt has both directions and magnitude.Higher the momentum, higher will be the Inertia.

Calculation:

Velocity has to be taken in m/s unit.

20 km/hr = 20 × (5/18) = 5.55m/s

Momentum = Mass × Velocity

=> Momentum = 5 × (5.55)

=> Momentum = 27.77 kg m/s

So final answer :

Momentum = 27.77 kg m/s
