36. Make Sense and Persevere The first astronaut on Mars tosses a rock straight up. The height, h.
measured in feet after t seconds, is given by the
function h(t) = -612 + 24 + 6. MP.1
(6--62 +24+ + 6
a. After how many seconds will the rock be
30 feet above the surface?
b. After how many seconds will the rock be
10 feet above the surface?
c. How many seconds will it take for the rock
to return to the surface?
d. The same action on Earth is modeled by the
equation g(t) --161? +24+ + 6. On Earth,
how many seconds would it take for the rock
to hit the ground?
