Here's a pseudocode and a flowchart for the equation x(t) = 0.5 * a * t^2 + v * t + x, where x is the initial position, v is the initial velocity, a is the acceleration and t is the time:
Pseudocode:
Read the values of x, v, a, and t.
Calculate x(t) using the formula: x(t) = 0.5 * a * t^2 + v * t + x.
Display the value of x(t).
