An aeroplane is flying vertically upwards. When it is at a height of `1000 m` above the ground and moving at a speed of `367 m//s`., a shot is fired at it with a speed of 567 `ms^(-1)` from a point directly below it. What should be the acceleration of aeroplane so that it may escape from being hit?
