A cannon launches a cannonball with initial speed $v$ at an angle $\alpha$ above the horizontal. Which equation gives the maximum height $H$ attained?

  • A$H = \frac{v \sin \alpha}{2g}$
  • B$H = \frac{g \sin \alpha}{2v}$
  • C$H = \frac{(v \sin \alpha)^2}{2g}$
  • D$H = \frac{g^2 \sin \alpha}{2v}$
