If a ball is thrown vertically upward with a velocity of 80 ft/s, then its height after seconds is =β. (a) what is the maximum height reached by the ball? (b) what is the velocity of the ball when it is 96 ft above the ground on its way up? (c) what is the velocity of the ball when it is 96 ft above the ground on its way down? if a ball is thrown vertically upward with a velocity of 80 ft/s, then its height after seconds is =β.

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.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27Β°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
