A comet fragment of mass 1.96 × 1013 kg is moving at 6.50 × 104 m/s when it crashes into Callisto, a moon of Jupiter. The mass of Callisto is 1.08 × 1023 kg. The collision is completely inelastic. Assuming for this calculation that Callisto's initial momentum is zero kg · m/s, what is the recoil speed of Callisto immediately after the collision?

Recoil speed,                          

Explanation:

Given that,

Mass of the comet fragment,

Speed of the comet fragment,

Mass of Callisto,

The collision is completely inelastic. Assuming for this calculation that Callisto's initial momentum is zero. So,

V is recoil speed of Callisto immediately after the collision.

So, the recoil speed of Callisto immediately after the collision is

answer: its c lololo
