WebFind the length of the curve. r (t)=2^1/2ti+e^tj+e^-tk, 0<=t<=1. calculus. The position vector r describes the path of an object moving in space. (a) Find the velocity vector, speed, and acceleration vector of the object. Position Vector: r (t) = ti + t²j + ½t²k Time: t = 4. WebTo find the velocity vector we have to differentiate r(t) with respect to time. r'(t) = 3t^2*i + 2t*j. The vector representing acceleration is the derivative of the position vector.

Curvature Recall that if C is a smooth curve defined by the vector function ~r(t), and ~r′(t) 6= ~0, then the unit tangent vector is given by T~(t) = ~r(t)/ ~r′(t) which indicates the direction of the curve. Since T~(t) pro-
