Momentum = MV

Now momentum doubled means that "Velocity is doubled"

keeping into account that "mass remains constant"

Hence new V₀ = 2V

K.E = (1/2)M(V₀)²

K.E (new) = (1/2)M(2V)² = 4 (1/2)MV² = 4 (k.e)

Hence if momentum is doubled then KE becomes 4 times initial KE.

Hope it helps.

Always available for help ! But Remember Don't hesitate to ask a good Question but Be damn serious for Questioning a weak one. <TABLE CELLSPACING="1" CELLPADDING="1" BORDER="0"> <TR><TD> <DIV ALIGN="right">Glitter Graphics</DIV></TD></TR></TABLE> [img]http://www.avatarsdb.com/avatars/fat_man_walk.gif[/img][url=http://www.avatarsdb.com/] [img]http://www.avatarsdb.com/avatars/angry_smile.gif[/img][/url][url=http://www.avatarsdb.com/] [img]http://www.avatarsdb.com/avatars/moon.gif[/img][/url]
