The initial velocity is obtained as 2.5 m/s.

<h3>What is the initial speed?</h3>

To obtain the initial speed, we have to apply the law of conservation of linear momentum which states that momentum before collision is equal to momentum after collision.

Now, the two fragments initially had one velocity before they were split in two directions opposite each other;

Applying the principle of conservation of linear momentum to this problem;

(2 + 10)v = (6 * 10) - (2 * 15) (they moved in opposite directions)

12v =60 - 30

12v = 30

v = 30/12

v = 2.5 m/s
