A particle travels through R3 and its position vector at time t is represented by the vector function r{t}. The particle's velocity and initial position are given by m) = 1-1:} = (t2 + 21:, 3 t, 1), and l'[}=(, %! 2)! respectively. Assume that the axes of R3 are sealed in meters and the time t is measured in seconds. Match the label under each gap with the correct number. - When t = 1. the magnitude of the particle's position vector is meters. {6} - When t : 1. the particle's speed is mfs. {5) - When it = 1. the magnitude of the particle's acceleration is mfs . {Cl
