Which statement explains the similarity between momentum and kinetic energy of an object? a. both are inversely proportional to the mass and velocity of the object. b. both are directly proportional to the mass and velocity of the object. c. both are inversely proportional to force and displacement. d. momentum is directly proportional to the mass of the object and the square of the velocity of the object. e. kinetic energy is directly proportional to the mass of the object and the square of the velocity of the object.

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:

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

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

Momentum of the body = P

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

where :

m = mass of an object

v = velocity of an object

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
