Terms can be used in once. Reset Hel the same as Both rocks are thrown from the same height. Therefore, the initial potential energy of Sandy's rock is smaller than the initial potential energy of Chris's rock. greater than The rocks have the same initial speed. Therefore, the initial kinetic energy of Sandy's rock is the initial kinetic energy of Chris's rock. So, the total energy of Sandy's rock is the total energy of Chris's rock. Both rocks reach the ground at the same height. Therefore, the final potential energy of Sandy's rock is that of Chris's rock. Therefore, the kinetic energy (and the speed) of Sandy's rock is that of Chris's rock.

The rocks have the same initial speed. Therefore, the initial kinetic energy of Sandy's rock is
the initial kinetic energy of Chris's rock. So, the total energy of Sandy's rock is
the total energy of Chris's rock.
Both rocks reach the ground at the same height. Therefore, the final potential energy of Sandy's rock is
