E-CodeKinematics: the five constant-acceleration equations — a TI-84 Plus CE program
SUVAT is a TI-BASIC program for the TI-84 Plus CE. Pick the two unknowns among s, u, v, a, t, type the other three (choose one direction as positive; s is the displacement): solves with the right SUVAT equation, and when a square root gives two answers shows each one with t ≥ 0.
What it asks for and what it shows
It asks for 3 values at its prompts, after you pick option 1 from its menu. In the example below it shows S (M), U (M/S), V (M/S), A M/S², T (S), SOLUTION.
Example run
One of its oracle test cases: “find s,u from v,a,t”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Menu | option 1 |
| Input 1 | 20 |
| Input 2 | 2 |
| Input 3 | 5 |
| The screen shows | |
S (M)= | 75 |
U (M/S)= | 10 |
V (M/S)= | 20 |
A M/S²= | 2 |
T (S)= | 5 |
| Text | SOLUTION |
How it's checked
8 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 54 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “Kinematics: the five constant-acceleration equations” (SUVAT).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
