**^Oblique projectile from ground**

Suppose a body is projected from the ground from point O at an angel q with the horizontal and with the velocity u. Let at time t the projectile is at point P where its velocity is v directed at angle b to the horizontal.

1 Using trigonometry x & y components of initial velocity are u_{x} = u cosθ & u_{y }= u sinθ

**Describing position **

2. Using vector addition law the position vector of point P w.r.t. origin is

3. Using s – t relation for the motion O to P along x & y axis we can write

(a) x – t relation: x = u _{x } t

(b) y – t relation: y =

Eliminating t from above two relations we get y – x relation:
