Section 13.1: Problem 3 (1 point) The equation ?(t) = (2 + 1')?+ (1'2 9)}: + (31') k gives the position of a particle in space at time 1'. Find the particle's velocity and acceleration vectors at time 1'. Then find the particle's speed and direction at time 1' = 3. 50') = _ 30') = _ Speed at timet = 3 is i Direction at time t = 3 is 555 Note: You can earn partial credit on this problem.
