    There is head-on elastic collision between the two particles moving in the same direction with speeds 5 m/s5\text{ }m/s and 3 m/s3\text{ }m/s respectively. After collision, the velocity of the first particle becomes 4 m/s4\text{ }m/s in the same direction. The velocity of the second particle should be
