kinetic energy question!
hey,
I have the following question to complete, and don't have the slightest clue where to start! :(
A sphere of mass 1kg, moving at 10 m/s, overtakes another sphere of
mass 5 kg moving in the same line at 3m/s. Find the loss of kinetic
energy during impact, and...
well for the length of the first particle 'A', i have: sqroot**( (2-11/13)^2 + (0-9/13)^2)**
which results in 3 sqroot*34*/13, is this correct so far? with mR^2, will 'm' represent the mass of each particle? if so, i get 7 41/169, different arithmetic :s thanks again!
thanks again for your quick reply! really helpful! :D
- for the length of each particle to the centre of mass I am using:
d = *squareroot* [ (a-x)^2 + (b - y)^2 ]
where (x , y) = centre of mass position and (a, b) = particles position.
Following this and using mR^2, I am getting...
oops! few mistakes there, yeah the correct answer would be (11/13, 9/13) ?? My axis is the centre of mass. how would I apply this to the system in this equation?
thank you so much for your help btw!

Hey everyone,
Im solving a group of questions based on a system of particles, A(2,0) with a mass of 4kg, B(0,1) with a mass of 6kg and C(1,1 ) with a mass of 3kg. I have to find the centre of mass and also calculate the moment of inertia.
To find the centre of mass I am attempting the...
