The ratio of maximum height reached by two bodies projected vertically upward with speed ratio x, y is

A

`x^2:y^2`

B

`x:y`

C

`sqrt(x):sqrt(y)`

D

none

Text Solution

Verified by Experts

The correct Answer is:
A
`H_("max") = u^2//2g`
`h_1 = (x^2)/(2g) , h_2 = (y^2)/(2g)`
`(h_1)/(h_2) = (x^2)/(y^2) = x^2 : y^2`
