Rahul Poddar 8 years, 2 months ago

Motion in horizontal direction u=ucos○ a=0 s=X from s=ut+1/2at^2 t=x/ucos○ Now motion in vertical direction u=usin○ a=-g t=x/ucos○ now from same equation s=usin○.x/ucos○ +1/2 (-g) x2/u2cos2● solving this we get s=tan●x-1/2 (g/u2cos2●) x2 which is a equation of quadratic so path of projectile is parabolic
