    Work out the velocity from the momentum?

    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

    How long did this car accelerate

    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...
