Ah thank you knew I was doing something wrong :blushing:

Homework Statement Two bodies A and B collide in a totally inelastic collision. Using the relevant equations and given that the mass of body A is 1200kg and the collision lasts for 0.2s, determine the average force vectors acting on each body during the collision. Homework Equations...

i was thinking the same thing sounds plausable. Has anyone looked at the simularitys between a 'white hole' and the big bang? mathmatically speaking of course

well i tryed google before hand with every variation i could think and have just tryed once again with no success

well i am supposed to be working out the resistance by putting a voltage through two oppisite faces of a brick i just need a measurable current so needed an appriopiate electro-motive force (voltage) does anyone know any where i can find this information or the resistance of a certain type brick?

what sort of voltage would i need to get a measurable current through a standard non uniform clay brick - where the current is in mA? thanks

if it does intract with normal matter why can't we find any by measureing its gravitational force and if there is soooo much of it wouldn't we directly feel its affects??

wow well that's kinda answered my question i was wondering about space battles at the speed of light which would include the 'going faster than light arguement' buts its all relative hehehe thanks for all ur posts :smile:

another question say you were traveling at 5 miles less than light and then you through a ball out of the side of your spaceship what will happen to the ball? would it just get heavier and larger n need more engery n infantly go up

well ok what i meant by no movement whatsoever was having (theorical) no gravitaional fields infact no forces acting on a person with a clock thanks for ur replys neways just me wondering what would happen IF you could travel at the speed of light (with the infinite amount of energy required)...

ok two question that kinda just have bugged me (im only 17 so this may all sound a bit basic!) ok traveling at the speed of light time is 0... as all the 'speed' is used up in 1 of the 3 space dimensions what would happen to someone traveling where the is no time? would they simply be...
