how do i go about in solving this?
A helium atom (mass 4.0 u) moving at 596 m/s to the right collides with an oxygen molecule (mass 32 u) moving in the same direction at 402 m/s. After the collision, the oxygen molecule moves at 445 m/s to the right. What is the velocity of the helium atom after the collision?

  • physics - ,

    total momentum before collision to the right=
    4*596 + 32*402

    total momentum to the right after collision=
    4*v + 32*445

    total momentum after = total momentum before so solve for v
