If a 2 kg ball is traveling at a speed of 4 m/s, what is its kinetic energy?
MariettaO [177]

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

<u>Some information about Kinetic Energy</u>.

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.
