vector r of a moving particle has the equation with respect to the origin of:
r(t) = (r/t^2)(t^2i - 2ttj + (t^2 + 2tt)k) where r and t are constants
show that the particle goes through the point P(4,-4,8)r. at what time does it do this?
what I did is i subbed (4,-4,8) into the equation but it didnt make anything clear to me, anyone any advice on how to tackle this problem?
Anyone know how id go about this, i need to find this part to complete parts b) and c) of which i know how to do which is the frustrating part!
i got the following:
r(4,-4,8)= (r/t)*(16i/t + 8j + (64/t +16)k)?
