CIN: A 3 B 9 C 6 D 4 E 5 CIN: 3 9 6 4 5 Problem A spacecraft moves along a path described by the parametric equations x=( 10 1+t 1 ) , y=40 t 4 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[b] seconds after launch. Round answers to one decimal place. Example: if [b] =3, then 1[b] =13 sec Solutions require DETAILED supporting work and explanations; answers alone are not sufficient. Please, explain your steps in full sentences and write the text of the questions. Steps and explanations should be easy to read (for example, use a column for steps and a corresponding column for explanations). Define the variables and set their values clearly. Write the formulas before you substitute any values. Number each problem in sequential logical order. You may refer to the textbook examples to see how to solve and present a problem. In summary, your post should not be just another piece of homework, but a place where present your math problems, kind like you would do in an English essay (use of APA where needed, accordingly with the grading rubric)
