A ball is projected from the ground with velocity `u` such that its range is maximum Then

A

Its velocity at half the maximum height is `(sqrt(3))/(2) u`

B

Its velocity at the maximum height is 'u'.

C

Change in its velocity when it returns to the ground is 'u'.

D

all the above are true.

Text Solution

Verified by Experts

The correct Answer is:
A
At half of max height
velocity `(V) =u sqrt((1+cos^(2) theta)/(2))`
