A projectile is launched on a planet other than Earth at a velocity of 36.4 m/s 30.0o above the horizontal. The ground slopes down in the direction of travel, so the projectile impacts the ground 37.7 m below the level from which it was launched. If the horizontal distance it travels is 337 m, what is the magnitude of the acceleration of gravity near the surface of the alien planet?

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. The same projectile was then fired in the same way toward a wall that is a horizontal distance (d) m from where the projectile was fired, and the projectile (as it's going down) hit the wall. If the wall were slightly farther from where the projectile was launched (the projectile...
