Dynamics
Hi! Pahelp please? Anyone who has a good heart huhuhu. I badly need your help. Anyone who can answer this? I mean with the process.
The collar has a mass of 3kg and is supported on the rod having a coefficient of kinetic friction Uk=0.4. The attached spring has an unstretched length of 0.2m and stiffness k=50N/m. Determine the speed of the collar after the applied force F=200N causes it to be displaced s=1.5m from pt. A. When s=0 the collar is held at rest?
What is the process?

Fluid mechanics
A hollow sphere 6 in inside diameter is rotated on a cable at 100 rpm. If the cable is 6 ft long and makes an angle of 30 degrees with the horizontal, what is the pressure in the center of the sphere if it is full of water? what is the equivalent specific weight at that point?

Present Economy
The Philippine Institute of Civil Engineers is planning to construct its own building. Two proposals are being considered:
(a) The construction of the building now to cost PhP 400,000.00
(b) The construction of a smaller building now, to cost PhP 300,000.00 and at the end of 5 years, an extension to be added to cost PhP 200,000.00
Which proposal is more economical if interest is 20%, depreciation is disregarded and by how much?
