How fast would a 6-g fly have to be traveling to slow a 1910-kg car traveling at 59 mph by 9 mph if the fly hit the car in a totally inelastic head-on collision?
Please I am trying to learn, so dont just give me the answer

Inelastic collision means simply that kinetic energy is not conserved, in the way that some kinetic energy is transformed into internal energy of the bodies that collide. This is important in some cool experiences, as in the Franck-Hertz experience where quantum mechanics must also be introduced.
Even though, momentum is conserved, so you can put
m_i*v_i = m_f*v_f where i is for initial and f for final.
so 0.006 * v + 1910 * 59 = 0.006 * 0 + 1910 * 50
and thus you find v. This gives a result bigger than the speed of light.
