Two identical cars collide head-on in a completely melastic one-dimensional colhston along
an x -axis. During the collisions, the two cars for a closed system. The component of the
initial velocity of car I along the x -axis is Vi1=+25 m/s, and that of car is Vi1=25 m/s
During the collision, the force (and thus the impulse) on each one causes a change in the car's velocity. The probability of a driver being killed depends on the magnitude of for that driver's car. What are the changes in the velocities of the cars. The total mass of car 1
is my 1400 kg, and the total mass of car 2 is 1400 kg​

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%)
