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 .

Step-by-Step Solution:

Step-by-step solution In this problem we have to calculate the force exerted by a chip of paint orbiting Earth and strikes an spacecraft consider the given data and give the proper solution respectively: Step 1 of 8 The expression of change in momentum is: …… (1) Here, is the mass and is the change in velocity. Step 2 of 8 The expression for exerted force is: …… (2) Step 3 of 8 Here, change in momentum and is equal to change in time. Step 4 of 8 The mass of the chip is 0.100 mg. So convert the mass in kg, Here is the relative speed of chip with respect to spacecraft window, and assume the initial speed of the chip is . So, the change in velocity is:
