Q.

A particle is projected from a pipe at an angle \(\theta = 45^o\) wtih the vertical at a point P with a speed \(u = 10 ms^{-1}\). A strong horizontal wind gives a constant horizontal acceleration equal to \(5 ms^{-2}\) to the particle such that the particle reaches the ground at point Q which is exactly below P. The height of point P (in m) from the ground is \([g = 10 ms^{-2}]\)
