What is the momentum of a 2 kg object moving at 15 meters per second

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.

Which describes an object in projectile motion? check all that apply. a.gravity acts to pull the object downb. the object moves in a straight path. c.the forward velocity of the object is 0 m/s. d.the object’s inertia carries it forward. e.the path of the object is curved.
