lol i never did this stuff :p

@TT, if you want, think about the dilations of the space-time diagrams as dilations of the angles that the axes make.

lolol yeah thanks i think i kinda get it, i dont understand the theory of this at all, im just gonna follow procedures kinda like a chem prac hahaha

[TrueTears]

hi can someone please show me how to do this question?

thanks

Interesting problem... I think this might work, though not sure

If the probe collides inelastically with space dust of mass , you can use conservation of momentum to find the final speed in terms of the initial speed:



Per hour, is probably too small to calculate on your calculator, so consider colliding with per day.

Then you can find , and use and apply Newton's third law

hey thanks for that help but the answers did this:

i dont understand it at all, can you explain it? or perhaps explain their solution better?

thanks

Oh that is a much better way of doing it...

The definition of force is , or , or

Since is constant, it becomes

thanks can you show me the numbers that are plugged in?

what is is the value of delta m? and if v is constant shouldnt the change in v = 0?

Delta v = v_final - v_initial = 0??

basically it is:

by product rule.

but since it is just .

oh i see, heh i dont apply any calculus to physics coz i dont bother understanding why, just using my broken vce knowledge
