1) Find the velocity and acceleration vectors of the particle whose position at time t seconds is given by s = (t',t, (3t-1) ) at the instant that t = 1. If distances are measured in meters, what is the speed of the particle at this time? (7 pts) 3 2) Find and sketch the graph of the domain of f (x, y) = (7 p 4x2 + 16y2 -64 3) Find the limit as (x, y) goes to (0,0) off (x, y) = = 6x2 y along the indicated 5 x*+ xy2 path. (10 pts) a) x = 2y
