Oscillating Table
Physics Help Please! *********Challenge of the day***********?
A 200g ball attached to a spring with spring constant
2.70N/m oscillates horizontally on a frictionless table. Its velocity is 22.0cm/s when x= -5.00cm.
A) What is the amplitude of oscillation? A= ???cm
B) What is the speed of the ball when x= 3.00cm? v= ???cm/s
Loosing my last nerve on this problem, please help!!!!
We need to assume that the equilibrium position is x=0
Then x(t) = A sin (omega t)
x'(t) = A omega cos (omega t)
The frequency of a mass on a spring is:
omega = sqrt (k/m)
sin(omega t) = x(t) / A
cos (omega t) = sqrt (1 - sin(omega t) ^2)
= sqrt (1 - (x(t) / A)^2 )
= x'(t) / A omega
A^2 - x(t)^2 = x'(t)^2 / omega^2
A = sqrt (m x'(t)^2 / k + x(t)^2)
They give you the mass, spring constant, velocity, and position. Plugnchug.
To get B), solve the equation above for x'(t) in terms of A (which is now known) and x(t).
x'(t) = omega^2 (A^2 - x(t)^2)
= k (A^2 - x(t)^2) / m

Things to Considering in Buying Hunter Ceiling Fans
You may need a little help choosing your Hunter ceiling fans. There are so many options and considerations that could easily be confused. You should know that the design of the fan is not his only point of concern. It is also necessary to consider factors such as room type and purpose of the fan. Find out how to choose the fan.
- One of the most important considerations is the size of the room. The room size is, of course, affects the air distribution. Small fans with blades less than 40 "or 30" are best for small rooms like bedrooms or bathrooms kid. Dens and kitchens on the other hand can be set in the middle range and should have the fan blades over 40 "large rooms and family rooms and recreation, should have leaves fans more than 50" or "60. < , br />
- The floor to ceiling height can also affect your choice of fan. For purposes of safety and comfort, ceiling fans must have a minimum of seven feet above the ground. If you have a very high ceiling, choose a Hunter fan that comes with a plain rod.
- The purpose of your ceiling fan, understandably, will affect your choice. Some fans are actually chosen for decoration than anything else. Of course, many people choose ceiling fans for functional reasons. For a purely decorative fan, you could go for one with a small engine and an intricate design. Fan models also differ depending on whether are for use indoors or outdoors.
- The choice of Hunter ceiling fans part be dictated by his sense of style. Of course, it makes sense to your style fan and the finish of the decor of your room and theme. If you have a lot of wooden furniture, you should opt for a Hunter fan with wood finish or dark finish. White blades on the other hand would be perfect for contemporary look. For added flexibility, you may want to get a Hunter fan with blades that can be reversed to show a different finish or color.
- Like other fans, models Hunter may also have other accessories. It is possible, for example, choose a fan that can be controlled by remote control.
- The lights can be incorporated into your ceiling fan. This may be a good idea because the fans are usually located in the center of a room. For fans of Hunter, just choose a light kit that matches your room design. You may have the option of lowering the optimum illumination of light availability. You can also receive up lights instead of providing a dimmer light in the room.
who believes there would be no-brainer when it comes Hunter ceiling fans. Start with these important considerations will surely find what you want.

Fan Black
Ceiling fan wiring - one black/one white wire from fan to one black/one white/one red wire from ceiling box?
I need to connect my new ceiling fan and light with remote that has one black, one white and one ground wire to my ceiling box that has one black, one white, one red and one ground wire. The room also has a single switch. Can someone let me know how to hook it up correctly?
You should be able to connect the fan white and the line white, and the fan black with the line black. Put a wire nut on the red and do not use it. (red would be if the switch was for a fan and separate light switch). The fan ground could be wrapped around the mounting screw of the ceiling box if there is no bare ground in ceiling box.
