A lift of very broad - floor is moving vertically upward with a constant retardation equal to 'g'. At an instant a stone is projected from a point on the floor of the lift at angle of elevation 0. Then the trajectory of the stone is:

A stone is projected with an initial velocity at some angle to the horizontal. A small piece separates from the stone before the stone reaches its maximum height. Then the piece will
