A particle is released from a certain height `H = 400m`. Due to the wind, the particle gathers the horizontal velocity component `v_x = ay "where a "= (sqrt5)s^(-1)` and y is the vertical displacement of the particle from the point of release, then find  (a) the horizontal drift of the particle when it strikes the ground ,  (b) the speed with which particle strikes the ground.
