A54.0-kg athlete leaps straight up into the air from a trampoline with an initial speed of 9.3 m/s. the goal of this problem is to find the maximum height she attains and her speed at half maximum height. (a) what are the interacting objects and how do they interacti? this answer has not been graded yet. (b) select the height at which the athlete's speed is 9.3 m/s as y = 0, what is her kinetic energy at this point? what is the gravitational potential energy associated with the athlete? (c) what is her kinetic energy at maximum height? what is the gravitational potential energy associated with the athlete? (d) write a general equation for energy conservation in this case and solve for the maximum height. substitute and obtain a numerical answer. (e) write the general equation for energy conservation and solve for the velocity at half the maximum height. substitute and obtain a numerical answer. m/s

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
