"Nate throws a ball straight downward, letting it bounce once before catching it. (we can ignore air resistance) A. what is true about the acceleration AND the velocity of the ball on its way down?
(assume upward is a positive direction)
1. Acceleration increases and velocity is negative and thus decreasing
2. Acceleration remains constant and velocity is negative and thus decreasing
3.Acceleration is decreases and velocity is positive and increasing
4. Acceleration remains constant and velocity is negative and decreasing

(What of the four suggestions is correct?)

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)
