Golf game, ball physics need help

HI

i am making a golf game and currently facing some problems with the physics of the ball.

var target : Transform;
var speed : float;
var force : float;
var angle = 50;

function FixedUpdate()
{
	if (target == null  GameObject.FindWithTag("hole"))
		target = GameObject.FindWithTag("hole").transform;
		
		if(Input.GetButtonDown("Jump"))
		{
		print("HIT");
		Hit();
		}
}

function Hit()
{
	var torque = Vector3(Input.GetAxis("Vertical"), 0, -Input.GetAxis("Horizontal"));
	var targetRotation = Quaternion.LookRotation (target.position-transform.position,Vector3.forward);
	transform.rotation = Quaternion.Slerp(transform.rotation,targetRotation,8);

	transform.eulerAngles.x = -angle;
        rigidbody.AddTorque(torque.normalized*speed);
	rigidbody.AddForceAtPosition (transform.forward * speed * force,target.position, ForceMode.VelocityChange );
}

the effect i am currently getting is something like this

and what i actually want would be like this

i have attached a rigid body to the ball and the rigid body properties are

mass 45
drag 0.5
annual drag 2
gravity true
is kinematic false
interpolate none
freeze rotation false
collision detection continuous

the problem i am facing is that once after hitting when the ball collides with the ground it bounces at the same position(the bounce reduces at every contact with the ground) and doesn’t move forward but actually what should happen is that the ball should move forward and the bounce should keep reducing on each collision with the ground

can anyone please help me out with this problem

thanks in advance

one more addition to the long story described above

once the ball goes in the air it is coming down very slowly so to solve this i had to increase the gravity(from the project settings-> physics)to a very big value somewhat around -5000(on the y axis) which i don’t think is logically correct,the ball is coming down fine now but i don’t think thats the right way to go about it. any suggestion on this would be really helpful .

thanks
