How to make object jump a specific distance ? Unity 3D

I’m a complete beginner so this might be simple. How can I make my player to jump to the end point of LineRenderer. So far I managed to make my player jump to the same direction that my LineRenderer points, but I want it to land at the end of the line.

I have this code:

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

public class Jump : MonoBehaviour
    public Rigidbody rb;
    public float height;
    public Vector3 pos1;   
    public Vector3 pos2;      
    public LineRenderer i0;
    public LineRenderer i1;
    public float power;

    void Start()
        pos1 = i1.GetPosition(1);
        pos2 = i0.GetPosition(0);

    void FixedUpdate()

        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began && IsGrounded())

    public void OnTouchJump(float power)
        Vector3 forceBB = new Vector3(0, 0, 0);
        Vector3 dir = pos2 - pos1;
        Vector3 n = pos1 + (dir / 2);
        n = n + new Vector3(0, height, 0);
        forceBB = n - pos1;
        rb.AddForce(forceBB * power);
    private bool IsGrounded()
       return Physics.Raycast(transform.position, Vector3.down, 0.5f);

I highly recommend looking at this talk. It’s a bit math heavy but it really helped me out on my game.

By having a LineRenderer point from your character to a target point (i.e. where you touch on the screen), this suggests a rather hands-off approach to making the jump. With that in mind, I would suggest taking a look at a previous post I made regarding trajectory.

Specifically, I could imagine that my examples of HitTargetBySpeed() or HitTargetByAngle() might be the sort of thing you’re looking for in this situation.
