A rock is thrown directly up with an initial velocity of Voy=28.8m/s at instant A as shown in the figure below. As it moves up it will reach a certain height h=9.8m at an instant B. It come back to the same height during it's fall from the maximum height at instant C. Determine the time it takes for the rock to go from B to C. Express your answer using one decimal place in units of seconds and take g=9.81m/s2.
