Answer:

  • Option D is the correct answer.

Explanation:

It is given that a 2 kg ball is traveling at a speed of 4 m/s, so we have to find its kinetic energy.

KE = 1/2 mv²

KE = 1/2 × 2×(4)²

KE = 1/2 × 2×16

KE = 16 J

Some information about Kinetic Energy.

Kinetic Energy is the energy an object has because of its motion. It is directly proportional to the velocity of the particle and its mass. Kinetic energy is given by,

  • KE = ½mv²
  • It occurs due to the motion of the particle.
  • If a particle at rest position, then the kinetic energy will be zero because that particle won't be accelerating.

The kinetic energy of the 2kg ball traveling at a speed of 4m/s is 16J.

KINETIC ENERGY:

The kinetic energy of a moving object can be calculated by using the formula as follows:

K.E = ½ × m × v²

Where:

K.E = kinetic energy (J)

m = mass of ball (kg)

v = velocity (m/s²)

According to this question, a 2 kg ball is traveling at a speed of 4 m/s, its kinetic energy can be calculated as follows:

K.E = ½ × 2 × 4²

K.E = ½ × 32

K.E = 16J

Therefore, the kinetic energy of the 2kg ball traveling at a speed of 4m/s is 16J.
