A mass of 2.5 kg is connected to a horizontal spring whose stiffness is 6.1 N/m. When the spring is relaxed, x= 0. The spring is stretched so that the initial value of x= +0.19 m. The mass is released from rest at time t= 0. Remember that when the argument of a trigonometric function is in radians, on a calculator you have to switch the calculator to radians or convert the radians to degrees. Predict the position x when t= 1.41 s:

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.
