A projectile is thrown with intial speed 'u'at angle o with horizontal. The projectile moves in x-y plane where 'x' axis is taken in horizontal and y-axis in vertical upward direction with origin being at point of proicction. Lagrangian of projectile is : 30. (a) - mu² - mgy (b) mx +j²)- mgy (0) m(3² +x²) + mgy (d) + mgy cos 0
