How fast must a 3000 kg elephant move to have the same kinetic energy as a 65 spinter running at 10ms?

Q. : How fast must a 3000 kg elephant move to have the same kinetic energy as a 65.0 kg sprinter running at 10m/s?

The elephant must be 1.47 m/s fast to have the same kinetic energy with the sprinter

Explanation:

Kinetic Energy: This is the energy of a body in motion. It can be expressed mathematically as

Ek = 1/2mv²

Since the kinetic energy the elephant = the kinetic energy of the sprinter.

1/2m₁v₁² = 1/2m₂v₂².......................... Equation 1

Making v₁ the subject of the equation,

v₁ = √(m₂v₂²/m₁)................................. Equation 2

Where v₁ = speed of the elephant, m₁ = mass of the elephant, v₂ = speed of the sprinter, m₂ = mass of the sprinter.

Given: m₁ = 3000 kg, m₂ 65 kg, v₂ = 10 m/s

Substituting these values into equation 2,

v₁ =√(65×10²/3000)

v₁ =

v₁ =

v = 1.47 m/s

Therefore The elephant must be 1.47 m/s fast to have the same kinetic energy with the sprinter
