A tennis ball, starting from rest, rolls down the hill in the drawing. At the end of the hill the ball becomes airborne, leaving at an angle of `37^(@)` with respect to the ground treat the ball as a thin-walled spherical shell.
Q. Range `x` of the ball is

Options

A. `(144)/(125)h`
B. `(48)/(25)h`
C. `(48)/(35)h`
D. `(24)/(7)h`

Explanation

`R=x=(2u^(2)sin37^(@)cos37^(@))/(g)`
`=((2)(6gh//5)(3//5)(4//5))/(g)`
`=(144)/(125)h`
