When I open my eyes, is the first thing I make with my eyes is the speed of light?
I mean, is what you SEE travel at the speed of light?
I hope you understand my question... T^T

A car is moving at 20 m/s [N] when it constantly accelerates to a final velocity of 10 m/s [E]. The magnitude of its displacement during this time is 1.50 X 10^2 m.

How long did the acceleration last?

My background is in Physics, and this is what I've been told. However, it doesn't seem to make sense to me. My position is the exact opposite, ie. - keep the spa close to the outside temperature and bring it up in temperature when using it. I'd like to hear what others think... with explanations, please.

when you transfer charged particles (in this case atomized paint) to a grounded surface, would you want the ground to have the least resistivity possible? i would imagine that you would want the least amount possible to transfer paint. we spray from 30-70 kv's at a distance of 1" for every 10 kv's. so if the resistivity is as low as possible, what could be the low points? the positive is better transfer of paint. i am new to electricity properties, so i would think as long as the resistivity is low on the ground part, then charged paint would be optimal process. i would like to know if i am wrong, or if there needs to be some resistance of the grounded part. BTW - the grounded part i refer to is plastic, and we create a bridge between the plastic and a metal rack with conductive primer. so the primer is really what i would need to know resistivity for. i need charged paint to go to the part and i think less resistivity would allow that if current could fully go to the ground.

What is the meaning of the cross product of two vectors? I know the dot product is what the two vectors have in common, but what physically does the cross product mean?

The longest recorded skid marks on a public road were left by a jaguar in a 1960 auto accident in USA and measured an astounding 290 m long. Assuming that the car had an average accelaration of -3.9 m/s^2 determine the jaguar's initial speed before the skid started.

I could really use the help (anything you know about cantaloupe launchers) because Ive never really built anything like this before... Also, it has to launch 10 meters.

A pendulum is swinging...now as time elapses from it's initial release, the strides taken by the pendulum decrease in length...is speed effected...or is time between the force of the release and the swinging only a factor w/ the length of the stride of the swinging pendulum?
