    1) Luigi launches a stone vertically upward from the top of a cliff. The height of the stone above the base of the cliff is appoximated by the model h=65+10t-5t^2
    where t is time in second and h is height in metres

    a) how high is the stone above the base of the cliff after 3 seconds?

    h = 65 + 10t - 5t^2
    h = 65 +10(3) - 5(3)^2
    h = 65 +30 - 45
    h = 50 m

    b) How long does it take for the stone to reach 50m above the base of the cliff?

    h = 65 + 10t - 5t^2
    h = 65 + 10t - 5t^2
    -65 + 50 = 10t - 5t^2
    -15 = 10t - 5t^2
    can someone help me from here?

    c) How long does it take for the stone to hit the ground at the base of the cliff?

    I do not know about how to go about completing this one,
