I need to determine how many pixels on my 72 dpi computer monitor an object will be taken from a camera with the following specs:
1/4" interlaced CCD
3.5mm to 91mm focal length
F1.6 to F4.0
26x optical zoom
angle of view: 1.7 degrees to 47 degrees
resolution: 704x576
I'm not to0...
PE of spring: (1/2)*k*x^2
PE of object on moon @ 100m: (6.154kg)*(1.625 m/s^2)*(100m) = 1000 J
So 2000 J = k*x^2.
Compressing a spring to 30cm, say, means that the spring constant would have to be:
2000 J / (.3m)^2 = 22,222.22 N/m. Did I do that right?
This would be a very stiff spring which...
I don't know much about springs, but it seems like I have the same problem in trying to figure out what characteristics of the spring are necessary to produce the required initial velocity of 18.03 m/s. What sort of spring constant and length are you talking about? How do you re-compress the...
So are you saying that if I just calculate the work done by an "engine" and have that work be 988 J, I will achieve the desired velocity? This is where I was getting confused. If I increase the stroke to 200cm then the work done by the solenoid would be 1000 J which would be enough? When...
Okay, I knew it wasn't so simple with what I was given. It may actually become very complicated. Let me reveal the operational concept/problem.
I need to figure out if it is possible to propel an object vertically from the surface of the moon using only electromechanical means. The thought...
Homework Statement
You have an object of mass 6.154 kg on the surface of the moon. What force is required to propel the object vertically to a height of 100m?
acceleration due to gravity on the moon (g): 1.625 m/s^2
Homework Equations
y = (v^2 - v0^2) / (2*g)
y: vertical displacement...
