A spacecraft moves along a path described by the parametric equations

x = 10 (1+⁴ -1), y=40t^3/2

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 spacecraft 1[3] seconds after launch. Round answers to one decimal place.

B =16 sec
