Two objects having equal masses are moving with uniform velocities of – InterviewSolution

1.

Two objects having equal masses are moving with uniform velocities of 2 m/s and 6 m/s respectively. Calculate the ratio of their kinetic energies.

Answer»

Let masses of the two objects be m

v₁= 2 m/s

v₂= 6 m/s

KE₁ = 1/2 m.(2)²

KE₂ = 1/2 m.(6)²

Ratio = (KE₁)/(KE₂) = 1/9
