    Motion in a Plane. Asked once: 12 May 2024 S2

    29
    A ball is projected vertically upwards from ground. It reaches a height hh in time t1t_1, continues its motion and then takes a time t2t_2 to reach ground. The height hh in terms of g,t1g, t_1 and t2t_2 is (gg = acceleration due to gravity)
