A cricket ball is hit for a six the bat at an angle of `45^(@)` to the horizontal with kinetic energy K. At the highest point, the kinetic energy of the ball is

A

`(3E)/(2)`

B

2E

C

`(sqrt 3E)/(4)`

D

`(3E)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
Kinetic energy at the highest point is K = `K_(a) cos^(2) theta`
`K=E cos ^(2)30^(@)=(3E)/(4)`
