A spark-ignition engine uses air as its working fluid. The compression process starts at a pressure of 1 atm and a temperature of 80 oF. The compression ratio of the cycle is 9. During the
heat input process, 650 Btu/lbm is added. Determine
(a) the temperature and pressure at the end of each process, (30 points)
(b) the thermal efficiency of the process, and (20 points)
(c) the mean effective pressure of the cycle. (20 points)

reserve is the answer

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
