Question Solved1 Answer 1. A particle moves in the xy-plane so that the position of the particle at any time t is given by x(t) = 2 e^(3) + e^(-7t), y(t) = 3 e^(3t) - ел(-2t). a. Find the velocity vector for the particle in terms of t and find the speed of the particle at t=0. b. Find dy/dx in terms of t and find lim as t approaches infinity of dy/dx. C. Find each value of t at which the line tangent to the path of the particle is horizontal, or explain why none exists. d. Find each value of t at which the line tangent to the path of the particle is vertical or explain why none exists.
