where:

$x(t)=x_0+v_{0}t+\frac{a{t}^2}{2}$

$20$ represents the position at time $0.$

$v_0$ represents the velocity at time $0.$

a represents the acceleration.

Assuming that:

all the required double variables $t,x0,$ v$0,$ and a have been declared and initialized to model all the different parameters;

a double variable $x$ has been declared.

Write a statement that assigns the position at time $t$ to the variable $x.$
