2. The range equation (see Cycle 2: Lecture 3: Page 4) can only be used if the projectile is launched from the ground and returns to the same height as it was fired from. What if instead it was fired from a given height, h? a) Find the range of an object

2. The range equation (see Cycle 2: Lecture 3: Page 4) can only be used if the projectile is launched from the ground and returns to the same height as it was fired from. What if instead it was fired from a given height, h? a) Find the range of an object fired from a height h and at an angle . b) Find the angle of launch which maximizes the range as a function of height.
