Find the magnitude and direction of the velocity and the

Question

A spacecraft moves along a path described by the parametric equations

x = 10 (√1+t⁴)-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 16 seconds after launch. Round answers to one decimal place.
