Acrate of 45.2-kg tools rests on a horizontal floor. you exert a gradually increasing horizontal push on it and observe that the crate just begins to move when your force exceeds 310n . after that you must reduce your push to 231n to keep it moving at a steady 25.2cm/s .
part a: what is the coefficient of static friction between the crate and the floor?
part b: what is the coefficient of kinetic friction between the crate and the floor?
part c: what push must you exert to give it an acceleration of 1.13m/s^2 ? (in n)
part d: suppose you were performing the same experiment on this crate but were doing it on the moon instead, where the acceleration due to gravity is 1.62 m/s^2. what magnitude push would cause it to move? (in n)
part e: what would its acceleration be if you maintained the push in part c?

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.
