Two identical grasshoppers jump with the same initial speed. Grasshopper A goes straight up, but grasshopper B goes up at a 66° angle above the horizontal. Assume no air resistance and choose your system to be grasshopper-Earth. Which of the following statements about these grasshoppers are correct? (There could be more than one correct choice.)
A) At their highest point, both systems have the same amount of gravitational potential energy.
B) At their highest point, both systemshave the same amount of kinetic energy.
C) At their highest point, both systemshave the same amount of mechanical energy.
D) At their highest point, grasshopper B is moving faster than grasshopper A.
E) At their highest point, the system grasshopper A-Earth has more gravitational potential energy than the system grasshopper B-Earth.
