Consider the motion of a projectile that is launched at certain angle and a speed from just below point A, and passes through point B and C before landing again just below point D. To further clarify, A and D are just above the ground. At what point(s) is the x-component of the ball’s acceleration (ax) equal to zero? Question 26 options:

A and D only

C only

ax is not zero at any point.

A, B, C, and D

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%)
