Physics Homework problem?
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 in newtons by a 0.150 mg chip of paint that strikes a spacecraft window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10−8 s. (Enter the magnitude.)

Calculate the force exerted in newtons by a 0.150 mg chip of paint that strikes a spacecraft window at a relative speed of 5.00 ✕ 10^3 m/s and sticks, given the collision lasts 6.00 ✕ 10^−8 s.

Ft = mv ->F = mv/t = (0.150 * 10^-6)* (5.00*10^3) / (6* 10^-8) = 12500N ( a bit over a tonne weight equivalent )
This is unrealistic because the paint splatters the glass flexes or chips. So it doesn't accurately represent the real situation.

5.00 ✕ 103 m/s 6.00 ✕ 10−8 s ?? these don't make sense. Please use proper format.
