A projectile is projected with a kinetic energy `K`. If it has the maximum possible horizontal range, then its kinetic energy at the highest point will be

A

0.25 K

B

0.5 K

C

0.75 K

D

1.0 K

Text Solution

Verified by Experts

The correct Answer is:
B
At highest point
`v. = v cos theta = v cos 45^(@) = (v)/( sqrt(2))`
(KE). ` = (1)/(2) mv^(2) = (1)/(2) m ( v^(2))/(2) = 0.5 KE. `
