Required Answer:-

We have:

  • Mass of the body = 0.2 kg
  • Initial velocity (u) = 5 m/s
  • Final velocity (v) = 17 m/s

To FinD:

  • Calculate the change in linear momentum of the body?

Step-wise-Step Explanation:

Linear Momentum can be defined as the product of mass and the velocity. Change in momentum = Final momentum - Initial momentum.

Initial momentum:

= m × u

= 0.2 kg × 5 m/s

= 1 kg m/s

Final momentum:

= m × v

= 0.2 kg × 17 m/s

= 3.4 kg m/s

Then, Change in momentum:

= Final momentum - Initial momentum

= 3.4 kg m/s - 1 kg m/s

= 2.4 kg m/s

Hence:-

  • The change in linear momentum of the body is 2.4 kg m/s (Answer)

Answer :-

✯ 2.4 kg m/s

Given :-

Mass of the body = 0.2 kg

Initial velocity (u) = 5 m/s

Final velocity (v) = 17 m/s

To find :-

Calculate the change in linear momentum of the body

SoluTion :-

Change in linear Mounmentum = Final Mounmentum - Initial Mounmentum.

 \huge \bf \: initial \:  \small(mounmentum) =  \huge \: m \times u

Initial Mounmentum = 0.2 × 5

➙ Initial Mounmentum = 1.0 or 1 kg

 \huge \bf \: final \small(mounmentum) =  \huge m \times v

➙ Final Mounmentum = 0.2 × 17

➙ Final Mounmentum = 3.4 kg

Now,

Finding change in linear Mounmentum

 \sf \: change \:  = 3.4  - 1.0

Change in Mounmentum = 2.4 Kg m/s
