6 A particle \(P\) is projected from a point \(O\) on horizontal ground. 0.4 s after the instant of projection, \(P\) is 5 m above the ground and a horizontal distance of 12 m from \(O\).
- Calculate the initial speed and the angle of projection of \(P\).
- Find the direction of motion of the particle 0.4 s after the instant of projection.
