Two frogs of equal masses jump into the air with the same initial speed. Frog #1 goes straight up, while frog #2 goes up at a 73° angle above the horizontal. Assuming negligible air resistance, which of the following statements about the two frogs are correct? (There could be more than one correct choice.) A) At their highest point, frog #2 is moving faster than frog #1. B) At their highest point, both of them have the same amount of gravitational potential energy. C) At their highest point, both of them have the same amount of kinetic energy. D) At their highest point, both of them have the same amount of mechanical energy. E) At their highest point, frog #1 has more gravitational potential energy than frog #2
