that doesn't work either the answer is asked for in 2 s.ds and in KW, so i assumed that would be 14, but that's not working

Homework Statement An elevator weighing 2100 N ascends at a constant speed of 8.0 m/s. How much power must the motor supply to do this? Homework Equations P = FvThe Attempt at a Solution F = 2100 N V = 8 m/s P = (2100) * (8) = 16800 in significant figures that's 1.7 x 10^4 w in kilowatts...

thanks once again you guys have helped a great deal. thanks alot, and i must say it is great to have such an awsome sorce of information from such a wonderful community. thanks: james

Forgive me if this is anything but trivial, but my physics teacher said in his lecture the other day that gravity has nothing to do with a pendulum coming to rest? how could this be? according to him, the reason for the pendulum coming to rest is air, but when i inquired about puting one in a...

this may be posted in the wrong place, but can sombody help me understand why time is relative? why should it not be absolute?

in my mind I am thinking if secured properly, this should (with the proper math) be able to help. i do trust your judgement, I am just wishing i could understand it. maybe when i actualy take physics next semester ill get a better idea, but right now I am just running off of information i have...

keeping in mind that i am a still in my first year more mass wouldn't lower the damages from this?

ya the inventions on the show are quite funny, but it was interesting to watch to see what would come up.

no i agree it would be bulky, but intuitively the science makes sense. instead of having to worry about the childs head smashing against somthing, the seat acts as a mothers womb and spins. look I am not saying this seat will ever see the light of day, I am more interested on what it would take...

lol i agree, unless it can be perfected, and this guy is working on perfecting it. intuitively this sounds like a wonderful idea, but we all agree that it is flawed. i feel it can be perfected with somthing as simple as more mass. am i wrong? im not worried about if it will be aproved, its...

but I am concentrating on the force acting on the car seat. not sure if you have seen the seat but it swings. if not google immage it, because on impact it flips. were worried about what will happen to all that force upon impact of the collision. i believe that the best way to decrease force on...

i trust you have all seen american inventor, and if not go look at the car seat on there because that is what this has to do with its bad, because the force has to go somwhere and probably it will hurt the child in the long run, but what if we could lower the amoung of force consider the...
