A particle starts at point (1, 0, 1) and moves 2 units along the curve defined by the vector equation r(t)=< e^t, sqrt(2)t, e^(-t) > positively. To find where the particle is after moving 2 units, we need to find the time T that the particle takes to move 2 units. What's the integral to find the time T?

Question
A particle starts at point (1, 0, 1) and moves 2 units along the curve defined by the
Expert Solution
Step 1
Given :
Distance traveled by the particle =2 units
The initial position of particle =
To find:- Time taken by particle to move 2 units in the integral form.
As we know that velocity is a vector function and velocity is given by
and the speed is given by
• Distance is the integral of speed so,
