Professional Application
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 4.00×103 m/s , given the collision lasts 6.00×10 – 8 s .

Problem 12PE
Professional Application
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 4.00×103 m/s , given the collision lasts 6.00×10 – 8 s .
ANSWER:
Solution 12PE:
Step 1 of 2:-
Mass of the chip of paint is, .
The initial velocity of the chip is, .
Let’s assume that the velocity after the collision is so small compared to the initial velocity, so that we can ignore the final velocity.
So, .
The lasting time for the collision is, .
