Question

find the kinetic energy of a particle of mass 20 moving with velocity 3i - 5j +4k

Answer 1

Answer:

The Kinetic Energy of the particle is 40 joules.

Explanation:

Given Data

Mass of the Particle = 20 kg

Velocity of the particle = (3-5+4) m/s

Find the Kinetic energy of the Particle

Velocity of the particle = (3-5+4)

Velocity of the particle = 3 - 1

Velocity of the particle = 2 m/s

The energy possessed an object when it is in motion is called the Kinetic Energy.

Kinetic energy is equal to the product of the mass and square of the velocity divided by two.

Substitute the respective values in above equation
