Question
One hazard of space travel is debris left by previous missions. There are several thousand objects orbiting Earth that are large enough to be detected by radar, but there are far greater numbers of very small objects, such as flakes of paint. Calculate the force exerted by a 0.100-mg chip of paint that strikes a spacecraft window at a relative speed of $4.00\times 10^{3}\textrm{ m/s}$, given the collision lasts $6.00 \times 10^{-8}\textrm{ s}$.

You state that the 0.100 mg chip is equal to 0.100 x 10^3 kg. I believe that you should have the mass as 1.00 x 10^-7 kg, or 0.100 x 10^6 kg, seeing as how 1 mg = 1 x 10^6 kg.
