oh no sorry I didn't realize that will I delete my post?

first translate all the points so that one rest on the origin (0,0) this can be easily done. take A(-1,1) and translate it to (0,0) by adding (1,-1) to it. this same translation must be used to change ALL the other points so B becomes (0+1,5-1) = (1,4) then C becomes (-2,-1) then draw your...

Thank you for all your help guys i did it again and got a value of 0.988c or 2.994*10^8 which sounds right to me as the lecturer told us it was close to the speed of light, thank you again

Homework Statement Moe measure the length of his spaceship as 350 m. Joe observes this spaceship as it flies by his position and measures that it took 0.700 s to pass through. What is the speed of the spaceship? l': the length of the spaceship as measured by MOE = 350m t: the time as...

ah i see now, that makes sense :D thank you very much for your help, i just got to get the basis for my numbers right, i was looking at the questions in the wrong way but now i see thanks again

This is a trick to see if i read the rules for the forum isn it? :P

But then all i would be doing is adding on the weight because the weight (M*g) is acting vertically downwards and the lift is accelerating vertically upwards which means the force must be acting upwards. the net force is surely 140 + the weight because these forces are acting against each other...

I noticed you mentioned there are other models which are competing, what other models are these? i would like to know of the other ideas and theories surrounding the higgs mechanism and would appreciate it if you explained more :D (simplified please)

thank you for your reply In what way would i calculate the force between the lift and the mass? would i just use 4 as the acceleration and go F = M * a F= 35 * 4 F= 140N would this be correct?

Homework Statement (in these questions we were told that g+ 10ms/s i know its not strictly true g should be 9.81 but our teacher told us to do this) 2. A 35 kg block rests on the floor of a lift. Find the force between the floor and the block if the lift (i) accelerates upwards at 4...

I've recently been told about the higgs boson or "god particle" I've heard it somehow endows particles with their mass, it interacts with the 'larger' (ones with more mass) more than the smaller particles and basically tells them how much mass to have, I am wondering how it does this and also I...
