^Horizontal projectiles 

^Horizontal projectiles 

Suppose a body is projected from some height from point O horizontally with the velocity u. Let at time ‘t’ the projectile is at point P (x, -y) where its velocity is v directed at angle b to the horizontal.

For the motion O to P along x & y axis we can write

Using s – t relation

1. x – t function: x = ut
2. y – t function: 
3. Using v – t relation
4. v_x – t function: v_x = u
5. v_y – t function: v_y = gt

From the velocity triangle of  v, v_x & v_y we get
