A 16 kg object with a velocity 7.5 m/s explodes into two equal fragments. One flies off with a velocity 2.5i -2.5j m/s.
What is the velocity of the other fragment in vector notation?

Momentum is conserved. With two masses, the second mass velocity must be the negative of the first.
V=-(2.5i-2.5j)
V=-(2.5i-2.5j)
