using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Swipeball : MonoBehaviour {

Vector2 startPos, endPos, direcion;
float touchTimeStart, touchTimeEnd, timeIntervl;

float throwForceInXandY = 0.5f, throwForceInZ = 100f;

Rigidbody rb;
// Use this for initialization
void Start () {
    rb = GetComponent<Rigidbody>();

}

// Update is called once per frame
void Update () {
    if (Input.GetMouseButtonDown(0))  // if (Input.touchCount>0 && Input.GetTouch(0).phase==TouchPhase.Began)
    {
        touchTimeStart = Time.time;
        startPos = Input.mousePosition; //Input.GetTouch(0).position;
    }

    if (Input.GetMouseButtonUp(0))// if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended)
    {
        touchTimeEnd = Time.time;
        timeIntervl = touchTimeEnd - touchTimeStart;

        endPos = Input.mousePosition; //Input.GetTouch(0).position;
        direcion = endPos  - startPos;

        rb.isKinematic = false;
        rb.AddForce(direcion.x * throwForceInXandY, direcion.y * throwForceInXandY, throwForceInZ / timeIntervl);
       // Destroy(gameObject, 3f);
    }
}

}

Hello,

how can i calculate the throwforce, depending off the speed from the swipe?

Many thanks
