Carefully observe the motion of the car on the way up. Does the acceleration change when the car leaves the copper sheet region on the tower, and if so, by how much? What would account for this change?
The SPEED changes on the way up, and it doesn't change by much, and it changes because of the brakes, if you look at it, you'll see that the bottom 1/3 of the tower has little things extending outward from where the car goes up from, those are brakes, so when it leaves the brakes, it goes slightly faster upward.
