Question

please answer this question ​

Answer 1

Given :-

• Mass = 250 g
• Velocity = 8m/s

To find :-

• Momentum = ?

We know that :-

• Momentum = mass × velocity

Solution :-

Firstly checking whether all units are in S.I. units ,

• Mass is not in S.I. unit

By converting ,

→ 250g to kg

→ 250g = 0.25 kg

• Velocity is in S.I. unit .

Substituting the values ,

☞ Momentum = 0.25 × 8

☞ Momentum = 25/100 × 8

☞ Momentum = 1/4 × 8

☞ Momentum = 1 × 2

☞ Momentum = 2 kgm/s

Hence , momentum = 2kgm/s

Answer 2

GIVEN:-

• Mass=250 gm=0.25 kg
• Velocity

TO FIND:-

Momentum

EXPLANATION:-

We know that:-

Momentum=Mass×Velocity

               or

p=mv

So let's put the data in the formula:-

Momentum=0.25×8

Momentum=2

SO THE MOMENTUM OF THE BODY IS 2 KG M/S
