# An object is projected vertically upward from ground level. It rises to a maximum height H. If air resistance is negligible, which of the following must be true for the object when it is at a height H/2 ?

An object is projected vertically upward from ground level. It rises to a maximum height \( H \). If air resistance is negligible, which of the following must be true for the object when it is at a height \( H/2 \) ?

- **A.** Its potential energy is half of its initial potential energy.
- **B.** Its speed is half of its initial speed.
- **C.** Its total mechanical energy is half of its initial value.
- **D.** Its kinetic energy is half of its initial kinetic energy.
- **E.** None of the above.
