In a game of football, a 94 kg player carries the ball and heads toward the opponent’s end zone with a
velocity of 6.0 m/s [W]. A linebacker delivers a vicious hit, causing the ball carrier to be knocked
backward with a velocity of 2.7 m/s [E]. Determine the impulse delivered to the ball carrier and the
force of the hit if it took the linebacker just 0.38 s to deliver the hit.

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.
