A projectile has been launched horizontally at 20.0 m/s from a height of 49.0 m. How far horizontally will the projectile fall? (You must calculate the time of flight by solving the equation below and then determine the distance by solving the formula v = d/t)

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
