6) time taken to reach opposite edge = (5+2)/(10 cos 30 degree)
= 0.8082 s
vertical height =ut-0.5gt^2 = 5*0.8082 -4.9*0.8082^2
= 0.8 m
vertical height on opposide side = 0.8+4 = 4.8 m
option b is correct
7) using second equation of motion
- 4 = 5t - 4.9t^2
t = 1.548 s
excess distance = 10*cos 30 degree *1.548 - 7
= 6.4 m
option e is correct

4. In the figure shown, rod AB (M-2 kg, L-2 m, center of mass C located 1 m above ground) is kept on a rough surface (H-0.5). A horizontal force F = 10 N is applied to the rod at point D, and distance CD-L/3 m. This horizontal force F causes the rod to rotate about B. Find initial linear acceleration of the top-most point A of the rod. Figure inset shows moment of inertia of a rod. Ignore air...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
