First find how the speed has changed when the Kinetic energy has decreased 2 times
So u see its 1/sqrt(2)times the original vo
then using the eq of motion 2gh=vf(2 in power) - vi (2 in power)
and putting vf=0 u can find h
In my course of modern Physics one postulate i read is
"Associated with any particle moving in a conservative field of force is a wave function which determines everything that can be known about the system"
A question arised in my mind is if the particle is moving in non conservative field...
the heading of this original post was Islam's war against islam this what western people think while in the islamic world people think its west's war against islam who are terrorists first we need to unnderstand that .People who reply to the Israeli tanks with stones are not terrorists people...
when i took physics major i didnt ask myself why? and now i think it is the kind of subject whose frequency match with my frequency (not in terms of c/wavelength) so i believe studying physics is like understanding nature n this curiosity is natural
"momentum is the measure of inertia "
and inertia is the property of the system or the object to resist a change in its state i.e either the state of motion or of rest
