A force of 1000 newtons is applied to the cannonball. But the code does not simulate correctly. I could not find my fault. I would be very grateful if you could help. Thanks.

@TOLGAHAN VARISLI, deleting questions after they've been answered is very much frowned upon and may limit the number of answers you get in future questions.
