Plot an equation of motion in 3D using (Parametic)Plot3D?

Hello everyone,

I've attached a picture of three coordinates. The teacher told me I have to Plot them in 3D getting a equation of motion. How could I get it? And what about the ParameticPlot3D?

Thank you!

Sorry, you are totaly right. I don't know but I really forget it.

So, I get this:

Block[
 {a = 0.05, T = 90, x1 = 0, y1 = 20, z1 = 40, x2 = 10, y2 = 10, 
  z2 = 0}, ParametricPlot3D[
  {x[t], y[t], z[t]}, {t, 0, T}, 
  AxesLabel -> {"x[t]", "y[t]", "z[t]"}, BoxRatios -> {1, 1, 1}, 
  PlotStyle -> Red
  ]
 ]

But how can I get a Plot3D (if I can)? 

Plot3D[{x[t], y[t], z[t]}, {t, 0, T}, ...]

Plot3D generates a 3D suface( or several surfaces at the same time) ,only ParametricPlot3D gives you parametric 3D curve (trajectory) ,or parametric 3D surface.
