Unable to edit time remapping for movement of object

Hello, I have an assignment to create a simple "movie" in Premiere Pro and I'm trying to make it appear as if the door is blown off the hinges. I got the correct movement in the clip, however the door moves slowly and looks as if its being drug to position, not blown off. Is there any way I can adjust the speed at which it moves to the new position. I've tried the time remapping feature, but as it's an image and not a video, that function is not available to me. Any advice would be greatly appreciated. I've attached screenshots showing the original position and ending position of the door. The picture also shows the time remapping feature grayed out. Thank You!
