Homework Statement
Two air track gliders of mass 0.30kg and 0.20 kg are moving towards each other with speeds of 0.50 m/s and 1.0m/s respectively. Take the direction of the more massive glider as positive.
A) if the collision is elastic, find the velocity of each glider after the collision.
Answer is: [ -0.70m/s , 0.80m/s ]
Homework Equations
m1v1 + m2v2 = (m1 + m2 ) v'
Ek = 1/2 mv2
for.. elastic equations i think..
Ek = Ek'
The Attempt at a Solution
I've tried using the v1' and v2' equations and subbing in the values, but the answer was not correct O_O. Uhm.. I just need a little hand on where to go next! (Note: I've also tried drawing the diagrams and I think they are correct xP) okay I've got one of the answers.. -0.7m/s but with that 1 equation.. how do I get the other answer lol...
