# Answer the follow

Answer :

A. An object of mass 2 kg moving with uniform velocity of 2 ms^{-1}.

Explanation: Momentum is defined as the product of the mass and the velocity of the object, i.e.

Where p is momentum of the object and m, v represents mass and the velocity respectively.

**Case 1:** Information from the question:

Mass of the object = **2 kg**

Velocity of the object = **2 ms ^{-1}**

Hence for momentum,

Momentum of an object = mass × velocity

= 2 × 2

= **4** **kg ms ^{-1}**

**Case 2:** Information from the question:

Mass of the object = **1 kg**

Velocity of the object =**3 ms ^{-1}**

Hence for momentum,

Momentum of an object= mass × velocity

= 1 × 3

= **3** **kg ms ^{-1}**

Now, momentum in **Case 1** is more than in **Case 2.** Hence we can observe that momentum is quantity which depends on both mass as well as velocity of the object.
