A projectile is being launched from ground level with no airresistance. You want to avoid having it enter a temperatureinversion layer in the atmosphere a height {\rm h} above theground.
1What is the maximum launch speed you could give this projectile ifyou shot it straight up? Express your answer in terms of {\rm h}and {\rm g}
2Suppose the launcher available shoots projectiles at twice themaximum launch speed you found in part A. At what maximum angleabove the horizontal should you launch the projectile?
3How far (in terms of h) from the launcher does the projectile inpart B land
