An astronaut throws a rock straight up from a cliff on a newly discovered planet. The height of the cliff is 12.16 m. The rock is thrown with an initial velocity of 8.2 m/s and hits the ground below the cliff 2.65 seconds later. y (m) x (m) What is the height of the rock, measured relative to the cliff top, at its highest point? (Note: Because the astronaut is not on Earth, the acceleration in the y-direction is not equal to −.)
