Motion In A Plane

Question
CBSEENPH11018513

A body is projected with velocity u at angle θ with horizontal. Write the expression for the path followed by body.

Solution

Velocity with which the body is projected = u 
Angle made by the body with horizontal = straight theta 
The equation of trajectory is given by, 
               straight y equals straight x space tanθ minus 1 half straight g fraction numerator straight x squared over denominator straight u squared cos squared straight theta end fraction
This is an equation of a parabole, hence the path of projectile projected at some angle with the horizontal direction from the ground is a parabolic path.
