Please answer number 6 only (Complete solution, with diagram/illustrate or analysis/explanation etc.) That would be soooo helpful and appreciated, thank you in advance!!*the previous answer is cropped, i cant see the full solution. e+50+150-806. An object whose weight is 100 lbf experiences a decrease in kinetic energy of 500 ft.lbf and an increase in potential energy of 1500 ft·lbf. The initial velocity and elevationof the object, each relative to the surface of the earth, are 40 ft/s and 30 ft, respectively.If g = 32.2 ft/s², determine:(a) the final velocity, in ft/s.(b) the final elevation, in ft.7.A closed system of mass 10 kg undergoes a process during which there is energytransfer by work from the system of 0.147 kJ per kg, an elevation decreases of 50 m,and an increase in velocity from 15 m/s to 30 m/s. The specific internal energydecreases by 5 kJ/kg and the acceleration of gravity are constant at 9.7 m/s².Determine the heat transfer for the process, in kJ.

6. An object whose weight is 100 lbf experiences a decrease in kinetic energy of 500 ft.
lbf and an increase in potential energy of 1500 ft·lbf. The initial velocity and elevation
of the object, each relative to the surface of the earth, are 40 ft/s and 30 ft, respectively.
If g = 32.2 ft/s², determine:
(a) the final velocity, in ft/s.
(b) the final elevation, in ft.
7.A closed system of mass 10 kg undergoes a process during which there is energy
transfer by work from the system of 0.147 kJ per kg, an elevation decreases of 50 m,
and an increase in velocity from 15 m/s to 30 m/s. The specific internal energy
decreases by 5 kJ/kg and the acceleration of gravity are constant at 9.7 m/s².
Determine the heat transfer for the process, in kJ.
