A canon shell fired breaks into two equal parts at its highest point. One part retraches the path to the canon with kinetic enegry `E_(1)` and the kinetic energy of the second part is `E_(2)`. Relation between `E_(1)` and `E_(2)` is

Options

A. `E_(2) = E_(1)`
B. `E_(2) = 4E_(1)`
C. `E_(2) = 9E_(1)`
D. `E_(2) = 15 E_(1)`

Answer

`(3)`

Explanation

At highest point according to L.C.M, `mu cos theta = - m/2ucos theta + m/2 v`
`E_(1) = 1/2(m/2)(u cos theta)^(2), E_(2) = 1/2(m/2)v^(2)`
