thanks for the formula... if two skaters collide 1 has 75kg mass (180kg ms^-1 momentum) and the other has 60kg mass (100 kg ms^-1 momentum) than the total size of momentum before the collision would be 206 kg ms^-1 right? I want to calculate the velocity of 206kg ms^-1 thanks
Homework Statement
Does anyone know if it is possible to work out the velocity from the momentum?
206Kg ms^-1 is the momentum... thanks

The Attempt at a Solution
ok thank u a lot for your help i also have another question:
the charge of one electron is -1.6x10^-19 am i correct?
so if i have a paint particle that carries 1.2 x 10^10 electrons (12000000000)what is the toatal charge it carries: i tried -1.6x10^-19 = -0.00000000000000000016 so i tried...
um yeah that's where its gets difficult cuause i don't know how.. I am not very good at physics... mayb u could show me a couple more tips...a few formulas or something
thanx
Hello
I need help with a question i am doing: A car accelerates at 2.4ms^-2 until it reaches a speed of 16ms^-1 how long did it accelerate for? and what distance did it travel while accelerating? could someone please help me...
Thanks
