A spacecraft moves along a path described by the parametric equations

x = 10 ((srt/1 + t⁴) 1 ) , y = 40 t^3/2

for the first 100 seconds 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 12 seconds after launch. Round answers to one decimal place.

Please show all the steps so I have a good understanding.

Thank you
