    pelican and fish both had u = + 0.50 m/s upwards

    ------------------------

    it is as if pelican threw fish downwards at

    u1 = - 0.50 m/s

    t = 2.5 s

    v(later) = u1 + gt

    = - 0.50 + 9.8*2.5

    = 24 m/s

    Ignoring wind resistance and assuming the pelican's ONLY velocity is vertical rising (very odd)...

    x''=-9.8

    x'=-9.8*t+.5

    x'(2.5)= -24 m/s or 24 m/s downwards
