it's potential energy will be maximum at heigest point.
U = mg X distance from the centre
= mgr ........(1)
from
v^2 = u^2 - 2 gr
0 = u^2 - 2gr
r = u^2/2g
then from (1)
U= mg X u^2/2g
= mu^2/2
U = mg X distance from the centre
= mgr ........(1)
from
v^2 = u^2 - 2 gr
0 = u^2 - 2gr
r = u^2/2g
then from (1)
U= mg X u^2/2g
= mu^2/2
