Answer 1

$\huge{\bold{\underline{\underline{....Answer....}}}}$

$\huge{\bold{\underline{Given:-}}}$

• Body A.

mass = m.

velocity = v.

• Body B

mass = m.

velocity = 2v.

(As their masses are equal)

$\huge{\bold{\underline{Explanation:-}}}$

a) Inertia

Mass is the measure of inertia and both the bodies have same masses

So, both the bodies have same Inertia.

b) Momentum

• Body A

$\large{\bold{P = mv}}$

$\large{P = m \times v}$

$\large{\boxed{P = mv}}$

So,the momentum of the body A is mv.

• Body B

$\large{\bold{P = mv}}$

$\large{P = m \times 2v}$

$\large{\boxed{P = 2mv}}$

So,the momentum of Body B is 2mv.

So,the body B has 2 times momentum that of Body A.

Answer 2

$\huge{\underline{\underline{\mathrm{Answer \colon}}}}$

From the Question,

Masses of the two particles are equal

Velocity of one particle is double to the other » v = 2v

Inertia

• Inertia of an object depends upon its mass

As the two objects have same mass,they inertia's would also be equivalent to eachother

Momentum

We Know that,

Momentum of an object is the product of its mass and velocity

$\implies \: \huge{\sf{p = mv}}$

Magnitude of Momentum:

Particle 1:

$\boxed{\sf{p = mv}}$

Particle 2:

$\boxed{\sf{p = 2mv}}$

Thus,The ratio of their momenta's is 1:2
