Physics - December 2006

Im looking for ideas on a physics project involving a car that must carry an egg, only using the power of a droping 3kg mass. The car must go 10m then come to a stop before hitting a wall. If you have any ideas let me know

a boat is pulled into a dock by a rote attached to the bow of the boat and passing through a pulley on the dock that is 1 meter high than the bow of the boat. If the rope is pulled in at a rate of 1 meter per second, how fast is the boat approaching the dock when it is 8 meters from the dock?

i wus thingking aboute this subject and had some iterestimg thoughts.when you move ,your time,space,and mass dialat.why.

hers what I thought.
when you move you gane kinetik energy
energy=mass
that meens that when you move you gane mass[1 down 2 to go]

if an object ganes mass,that objects gravitational pull gets stroger
gravity "bends" space time.
bend in space time=space/time dialation?

can I have some help cleening this up.I dont know wher to go frome here

I have a graph of velocity versus time for constant acceleration after looking at the graph I have to fill in a chart with four headings in each column: TIME (s), VELOCITY (m/s), ACCELERATION (m/s^2), AND DISPLACEMENT (m). There are 4 rows under time and velocity. In the column that says time here is whats given 0.0, 2.0, 5.0, and 10.0. I got the velocity by looking at the graph. Heres what I got. At time 0.0 the velocity is 1.0 at time 2.0 the velocity is 2.0 at time 5.0 the velocity is 3.5 and at time 10.0 I got 6.0 under the heading acceleration and displacement there are only 3 rows. Heres what I got:
At time 0.0, velocity 1.0 acceleration is 0.5, at time 2.0, velocity 2.0, the acceleration is 0.5 at time 5.0, velocity 3.5, the acceleration is 0.5. what I wanna know is does this sound correct? Do the velocity and acceleration make sense according to the time given? Also how would I calculate the displacement for these 3 is there a formula I use to calculate the displacement? Please help im having dificulty understanding this problem and I still have one more with a graph of velocity versus time for motion with variable acceleration. Please show ur work and explain thoroughly. Maybe drawing a table with the info I have given may help u understand the question if it doesn’t make sense in the way I wrote it.

im not even sure thats the right thing...i have these odd blips...i get a lot of electric surges...when its stormy my hands and often my arms feet even head get all tingley...i get electric shocks from walking down the road sometimes and it kind of comes up through my feet and sometimes my hand feel like they are getting little electric shock...i have even kissed people before and actually had a shock...i kissed my son once and there was actually an electrical spark...amazing...my energy levels also soar during stormy weather and just before it too...

aside from that i also get this thing where certain things work in a peculiar fashion...if a cd jumps on the stereo...i kid you not if i walk over and lay my hand gently on top of the stereo it rights itself...as soon as i take it away it starts jumping again...also motion sensored taps dont work at all for me...is this all daft or is it an energy thing?...someone said to me that it could be a magnetic field thing...can anyone explain?

I have a project in my science class and I had to build a thrill ride.
I built a water slide, but I need to write a paper that says how many G-forces a rider of this ride will experience.

Does anyone know how I can figure out how many G-forces are on this ride?

A weight lifter lifts a set of weights a vertical distance of 2.00m. If a constant net force os 350N is exerted on teh weights, how much work does the weight lifter do on teh weights?

Wnet = (350N) (2.00m) (cos 90) = 0 J

Is this correct?

Is the classic description of electricity travelling in a circuit based on electrons whizzing around at the speed of light? If so, regardless of the low resistance of the cables, why don't the wires in my walls get incredibly hot? In a lightbulb the high resistance of the filament "slows down" the electrons causing them to give off energy in the form of heat and light. This doesn't make sense to me. If electrons are "bumping into" tungsten in the lightbulb they must also be "bumping into" copper in the cables. Due to the numbers of collisions and the speeds involved, surely huge heat should be generated? Does anything actually "move" around a circuit? Let's call an electron "John". Does John move from point A to point B which is further along the circuit, then to point C etc. etc.
If not, what exactly is moving through the cables? Or is the classical picture just inadequate to describe the transfer mechanism(s).
