    At time t = 0, two balls A and B are projected vertically upwards. The ball A is projected
    vertically upwards with speed 2 m s–1 from a point 50 m above the horizontal ground.
    The ball B is projected vertically upwards from the ground with speed 20 m s–1. At time
    t = T seconds, the two balls are at the same vertical height, h metres, above the ground.
    The balls are modelled as particles moving freely under gravity. Find
    (a) the value of T,
    (5)
    (b) the value of h.
    (2)
    I understand you have to use the equation s=ut+1/2at^2 and then make the equations for both balls equal to eachothers to find t however i can't seem to do it correctly.
