Module 5 - Discussion: Application CIN Problems A spacecraft moves along a path described by the parametric equationsx=10(1+t41), y=40t32for the first 100 sec after launch. Find the magnitude and direction of the velocity and the resultant acceleration of the spacecraft 12 seconds after launch. 41°1+t4¿32¿a=dVdt=20t2(t4+3)¿ .
