Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points Suppose that you are going to program a computer to carry out an iterative calcula- tion of motion involving non-constant forces. Which of the following calculations should be done before starting the repetitive loop calcu- lations? (A) Define constants such as G. (B) Update the (vector) position of each ob- ject. (C) Calculate the (vector) forces acting on the objects. (D) Specify the initial (vector) momentum of each object. (E) Specify an appropriate value for the time step. (F) Specify the mass of each object. (G) Update the (vector) momentum of each object. (H) Specify the initial (vector) position of each object. 1. B, C, F, G 2. A, E, H 3. B, F 4. B, D, F 5.
