    Use the same equation to solve for t, with different parameters. v=+54'/s x0=40' don't forget to correct the half-acceleration from -4.9 to -16.1'/s^2

    X0 is the initial height, taking ground level as 0'.

    Sorry, you got the wrong guy or the "just answer" responses. See also code of conduct : "I will encourage and guide those needing help, and not just give them an answer"

    You're welcome! Remember, you only have to find the values and substitute into the given kinematics equation.
