A4 Curves: Problem 12 Previous Problem Problem List Next Problem (1 point) Given that the acceleration vector is a (t) = (-25 cos(-5t), -25 sin(-5t), -t), the initial velocity is v(0) = (1, 0, 1), and the initial position vector is r(0) = (1, 1, 1), compute: A. The velocity vector v (t) = it j+ k B. The position vector r (t) = it k Note: Your answers must be functions of t; e.g., "5 cos(2t)"
