2. A 12 gram steel projectile is shot horizontally at 20.0 m/s from the top of a 49.0 m high tower. How far from the base of the tower does the projectile hit the ground? What angle is needed to reach the furthest distance
away from the tower? If the original projectile was replaced with a steel projectile with a 20 gram mass how far
from the base of the tower would the new projectile hit the ground?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
