A 9 mm Xian short-barreled experimental pistol is fired and the explosive gases push the friction-free bullet out of the gun barrel. The gas pressure is carefully recorded as the bullet accelerates towards to exit, with the collected data shown below. What is the work done on the bullet? How does this change if the gun is pointed directly into the air vs horizontally?

Bullet position from initial (cm)	0	2	3	4	5	6	7	8
Pressure in gun chamber behind the bullet (bar)	23	25	24	22	17	10	6	4
