1. The problem statement, all variables and given/known data A body is moving, with the following data (these are all dependencies of the radius vector components respective to time): x(t)=At2, A>0; y(t)=Bt, B>0, z(t)=0. How does the trajectory of this movement look? 2. Relevant equations r=x(t)i+y(t)j+z(t)k Velocity=dr/dt 3. The attempt at a solution r=At2*i+Bt*j (i,j and r are vectors) Velocity=2At*i+B*j Intuitively I think that the trajectory would look like a logarithm function, but is it correct and how to prove it?
