A particle is released from a certain height `H=400m`. Due to wind the particel gathers the horizontal velocity component `V_(x)=a y` where `a= sqrt(5)s^(-1)` and y is the vertical displacement of the particle from point of release. Then (a) Horizontal drift of the particle when it strikes the ground (b) The speed with which the particle strikes the ground are p(2.67) km, q(0.9)km/s. The values of p, q are
