Member warned to use the homework template for posts in the homework sections of PF.

The equation of trajectory of ball B is y = -0.05x^2 where y is vertical displacement and x is horizontal. Prove that the ball is projected horizontallyFor this, the mark scheme says

x tan a = 0 so a =0

Since the angle between ball and surface is 0 the object is projected horizontally.

I can't work out how is x tan a = 0

x tan a = 0 so a =0

Since the angle between ball and surface is 0 the object is projected horizontally.
