AI Thread Summary
To determine how long it would take to deflect an asteroid on a collision course with Earth using a 2000N thruster, key factors include the asteroid's mass and velocity, which are crucial for calculating the necessary force and time for deflection. The required change in trajectory is specified as 12 Earth diameters, necessitating precise calculations involving Newton's laws of motion. Without the mass of the asteroid, it is challenging to apply the appropriate equations effectively. Additional information about the asteroid's size and speed is essential for a comprehensive solution. Understanding these variables will enable a more accurate assessment of the deflection time.

Hello all,

I am really having trouble with following. I want to find the answer myself, but i do not know what equation/s i should apply to solve the problem.

My Question.

How long will it take to deflect an asteroid on a collision course with Earth by attaching a 2000N thruster. I must change the course of the asteroid by 12 Earth diameters.

Thank you in advance

This should be in the homework help section. Also do you have more information, such as the mass of the asteroid?
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
