The man falls H-h distance.v^2 - u^2 = 2as ; u=0v = { 20 (H-h) } ^ .5Find time taken to fall the remaining distance i.e. h.This is the time in which he needs to cover horizontal diastance x. thus find horizontal velocity needed.Conserve momentum, mv =MV [v is speed at which bag is thrown & V is speed that the man gains]Calculate v.
