change bounce height of physics object

hey guys, I m currently working on a small game where i want a sphere to performe a ground slam. Currently I add an Impulse to the ball to send it to the ground but how can I make that he doesnt fly up 10km? I already tried to change the mass but when I did that it eighter did nothing, I fell trough the floor or It worked some how once.

You could use a thruster. Constrain the sphere on maybe x and y axis and position the thruster along z axis pointing downward. You can deactivate the thruster until you need it and then activate it to send ball to the ground. The thruster will probably hold the sphere to the ground but you could also deactivate the thruster after hitting the ground for a different behavior. You wouldn’t need the Impulse for this idea.
