Can we use conservation of energy law to find final velocity
Homework Statement It's a simple problem, you kick a ball with an initial velocity of 5.4 m/s, the angle is 30 degrees. So the question is when does it land on the ground? So I thought that I could find final velocity so that I can use V = V(initial) + acceleration * time. My question is, can...- justduy

When does the plate of glass loosen from a glass cylinder in water?
I understood it now. I mistook some information given by the book. I wasn't able to see the difference on p and greek letter ro. I understand now that there is pressure or force affecting the whole glass cylinder, both from the water on the glass cylinder and the ethanol on the glass cylinder.- justduy

When does the plate of glass loosen from a glass cylinder in water?
It says nothing about what kinds of forces that are in play. The only thing we get to know is that: the plate of glass is pushed at the end of the cylinder of glass which is then put under water.- justduy

Hydraulics and pressure problem
Homework Statement The hydraulic system is this: It has two stamps (Unsure of how I am to translate that word). Basically it is the plate on which we apply pressure. You apply pressure on one of them, the other goes up. The question is: How high will the big stamp move upwards when the small...- justduy

When does the plate of glass loosen from a glass cylinder in water?
Homework Statement A thin glass plate is pressed at the end of a glass cylinder. The glass cylinder with the glass plate at the bottom is dipped in water so that the plate is 25 cm under the water surface (The glass cylinder i open, meaning only the bottom part is closed, due to the glass...- justduy
