How could i attach 2 servo to one arduino uno to different function?

i have arduino uno and 2 servo motor ,one of them attached to ultra sonic sensor and rotate from 0-180 and return"radar" i used “processing apps” to interface targets
how could i make second servo to point to the target (second servo connected to rocket model) by angle

i uploaded 2 codes that i used

#include <Servo.h>

const int trigPin=9;
const int echoPin=10;

long duration;
int distance;

Servo s1;

void setup() {
  
  Serial.begin(9600);
  pinMode(trigPin,OUTPUT);
  pinMode(echoPin,INPUT);

  s1.attach(11);
}

void loop()
{
    for(int i=15;i<=165;i++){            // rotates the servo motor from 15 to 165 degrees
    s1.write(i);
    delay(30);
    distance = calDist();

    Serial.print(i);                      // Sends the current degree into the Serial Port
    Serial.print(",");                   // Sends addition character right next to the previous value needed later in the Processing IDE for indexing
    Serial.print(distance);                // Sends the distance value into the Serial Port
    Serial.print(".");                   // Sends addition character right next to the previous value needed later in the Processing IDE for indexing
      }

    for(int i=165;i>15;i--){  
    s1.write(i);
    delay(30);
    distance = calDist();
    Serial.print(i);
    Serial.print(",");
    Serial.print(distance);
    Serial.print(".");
    }

}

int calDist()
{
   digitalWrite(trigPin, LOW);
   delayMicroseconds(2);
                                                                // Sets the trigPin on HIGH state for 10 micro seconds
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW); 
                                                              // Reads the echoPin, returns the sound wave travel time in microseconds
  duration = pulseIn(echoPin, HIGH);
                                                              // Calculating the distance
  distance= duration*0.034/2;                                // Range : 2cm to 400 cm

Hi sheriffouad, welcome to the forum. Rather than attaching the code, include it in your post using the code tags. This will help us see your code without the need to download files.

Don't know what code tags are? Read up about it here

You will need to develop some serial receive routines: https://forum.arduino.cc/index.php?topic=396450 and then send data from Processing to the board
