Answer 1

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

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
