A rocket moves along a path described by the parametric equations 3 x 10( 1 t 4 1), y 40t 2
for the first 100 sec after launch. Here, x and y are measured in meters, and t is measured in seconds. Find the magnitude and direction of the velocity and the resultant acceleration of the rocket
18 seconds after launch. Round answers to one decimal place.
