As part of a carnival game, a =0.578 kgmb=0.578 kg ball is thrown at a stack of 25.3 cm25.3 cm tall, =0.363 kgmo=0.363 kg objects and hits with a perfectly horizontal velocity of ,i=12.3 m/s. vb, i=12.3 m/s. suppose the ball strikes the topmost object. immediately after the collision, the ball has a horizontal velocity of ,f=4.85 m/svb, f=4.85 m/s in the same direction, the topmost object has an angular velocity of =2.03 rad/sωo=2.03 rad/s about its center of mass, and all the remaining objects are undisturbed. if the object's center of mass is located =17.7 cmr=17.7 cm below the point where the ball hits, what is the moment of inertia of the object about its center of mass?

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.
