Question

One hazard of space travel is the 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 4.00×10^3 m/s, given the collision lasts 6.00×10^8s.

Answer 1

F = 6666.7 N

Step-by-step explanation:

Given that,

Mass of a chip, m = 0.1 mg

Initial speed, u = 0

Final speed,
`v=4* 10^(3)\ m/s`

Time of collision,
`t=6* 10^(-8)\ s`

We know that,

Force, F = ma

Put all the values,

`F=(m(v-u))/(t)\\\\F=(0.1* 10^(-6)* (4* 10^3-0))/(6* 10^(-8))\\\\F=6666.7\ N`

So, the required force is 6666.7 N.
