A bike of mass 100kg and a car of mass 500kg are moving at the same speed.Find the ratio of their kinetic energy

Open in App

Solution

Dear Student

We know that kinetic energy is given as E = (1/2)mv²

In case of Bike

E₁ = (1/2)mv² = 1/2 × 100 × v²

and

In case of Car

E₂= 1/2 × 500 ×v²

Ratio will be

E₁/E₂ = [1/2 × 100 × v²] / [1/2 × 500 × v²]

E₁/E₂ = 1/5

Ratio is 1:5
