Write a general algorithm for as1 (x values only):

1. initialize values
   - set t = 0
   - set x acceleration = 0

2. get inputs
   - get initial x position from user
   - get initial x velocity from user

3. do calculation
   - calculate nex x position for t = 0

4. output result
   - output new x position and current t value

5. increment t by one

- repeat steps 3, 4, and 5 until t > 4
   - For now we can just copy-and-paste these steps for each value of t. Later,
     we will learn to use a loop construct to make this less tedious.
