Two bodies of masses m1 and m2 fall from height h1 and h2 respectively.The ratio of their velocities,when they hit the ground is?

Question

options are

under root h1/h2

h1/h2

m1h1/m2h2

h1^2/h2^2

 ans is the underroot one

Answer 1

Correct answer is: √(^h1/_h2)

Masses m1 and m2 are immaterial to the solution of this particular problem. Here a simple explanation:

h1=(1/2)gt₁²
h2=(1/2)gt₂²

V₁=gt₁
v₂=gt₂

V₁/V₂ = t₁/t₂ = √(^h1/_h2)

 

Hope this will help.
