### Background Questions

Compared to other (non-coding) activities in this course at your school, how difficult was it to complete the planetoids coding exercise?

How easy or difficult did you find using the stemcoding.osu.edu website to view the tutorial and then modify, run and submit your code?

Was the programming lab fun?

### AFCI Questions 1 and 2

Use the animations below to answer questions 1 and 2.

A rocket drifts sideways in outer space from point "a" to point "b" as shown in the animations. The rocket is subject to no outside forces. Starting at position "b", the rocket's engine is turned on and produces a constant thrust (force on the rocket) at right angles to the line "ab". The constant thrust is maintained until the rocket reaches a point "c" in space. Which animation (A through E above) best represents the path of the rocket between points "b" and "c"?

### AFCI Question 1

Which animation best represents the path of the rocket between points "b" and "c"

### AFCI Question 2

As the rocket moves from position "b" to position "c" its speed it:

### AFCI Questions 3 and 4

Use the animations below to answer questions 3 and 4.

A rocket drifts sideways in outer space form point "a" to point "b" as shown in the animations from the previous two questions. The rocket is subject to no outside forces. Starting at position "b", the rocket's engine is turned on and produces a constant thrust (force on the rocket) at right angles to the line "ab". The constant thrust is maintained until the rocket reaches a point "c" in space. At point "c" the rocket's engine is turned off and the thrust immediately drops to zero.

### AFCI Question 3

Which animation best represents the path of the rocket beyond point "c"?

### AFCI Question 4

Beyond position "c" the speed of the rocket is:
