On my bike, i was able to travel 40 miles in one hour. from this information, we can determine the bike's

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.

An air standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes. 1-2 isentropic compression 100 kpa and 22°c to 600 kpa 2-3 v=constant heat addition to 1500 k 3-4 isentropic expansion to 100 kpa 4-1 p=constant heat rejection to initial state (a) show the cycle on p-v and t-s s (b) calculate the net work output per unit mass (409 kj/kg) (c) determine the thermal efficiency (47.9%)

An astronaut on the moon throws a baseball upward. the asatronaut is 6ft, 6in. tall, and the initial velocity of the ball is 30ft per second. the heigh s of the ball in feet is given by the equation s = -2.7^2 + 30t + 6.5, where t is the number of seconds after the ball was thrown. after how many seconds is the ball 16ft above the moon's surface?
