Part A Fil in the missing line Below is a program that models the motion of a rocket. If you look down in the "While" loop, you will notice that one line is missing in the program. Type in the line of physics that belongs at the point where the comment indicates the missing line should be # This program models the motion of a rocket that # starts at zero velocity and has a variable thrust # of Ft-10000 t Netw ons for the first 10 seconds. from visual import m-1000 #kg g-_9.8 #m/s/s Fg-vector(0.0, m"g, 0.0) #N t 0.0 #sec dts 0.1 #sec s-vector(0.0.300.0.0.0) #m v-vector(0.0.0.0.0.0) #mis while t
