Answer 2

Answer:

The correct answer is option B.

Explanation:

Kinetic energy is the energy of the an object due to its motion.The kinetic energy of an object in motion is given as:

$K.E=\frac{1}{2}mv^2$

As we can see that kinetic energy is directly proportional mass and velocity of an object.

• K.E ∝ m
• K.E ∝ v

Momentum  is the quantity of the motion possessed by the motion in object .

Momentum of the body = P

$P = m\times v$

As we can see that momentum is directly proportional mass and velocity of an object.

• P ∝ m
• P ∝ v

where :

m = mass of an object

v = velocity of an object
