Change speeds with collisions with trampoline?

Unity Engine
1

So I want my player to fall and collide with an object thats still. I want my player to fly back up and fall down after collision and i want the object to start moving left and right at different speeds each time they collide. I got my object to float left and right I just dont know how to get it to change speeds and push the player back up. Any wise sage would be appreciated. My code so far

using UnityEngine;
using System.Collections;

public class Floater : MonoBehaviour {

	public float floatSpeed = 2.0f;
	public float wallLeft = 0.0f;
	public float wallRight = 5.0f;
	
	float floatingDirection = 1.0f;
	Vector3 floatAmount;
	
	// Update is called once per frame
	void Update () {
		
		floatAmount.x = floatingDirection * floatSpeed * Time.deltaTime;
		
		if (floatingDirection > 0.0f  transform.position.x >= wallRight)
			floatingDirection = -1.0f;
		else if (floatingDirection < 0.0f  transform.position.x <= wallLeft)
			floatingDirection = 1.0f;
		
		transform.Translate(floatAmount);
	}
}

You need to implement a spring. Accelerate your object upwards in proportion to how far it has passed the trampoline plane. The standard spring equation ( force = springConstant * distance) should work just make sure it’s one-sided (i.e. doesn’t apply downward velocity).

Read this link to do the integration properly. It is about jumping but the same will apply to spring forces. Using simple forward integration always accumulates error in the same direction. You just want to average the error in both directions a bit. It is not perfect, but it is fast and less sensitive to changes in frame rate.

Well I dont want it to spring up I want him to collide. Dissappear for a second then be launched back up while the launcher changes its speed
