In this problem, we have a sports car traveling at 100 miles an hour, and it's going over a hill that is, let's see here.
00:20
We have it, it's going over this hill, and so we have something like it's coming up with hill, and the hills rounded off at the top, and so then we have a radius of curvature for this, this hill here.
00:35
And that radius is something we are needing to determine.
00:42
Now, the, let's see here.
00:46
The car, the initial car, the sports car weighs 2 ,400 pounds.
00:59
And let's see here.
01:03
All right.
01:04
And the, it's going at, let's see here.
01:10
I didn't write that down.
01:12
V was 100 miles per hour, and that equals 147 feet per second.
01:25
All right.
01:27
So let's see here.
01:30
We have, we're told that as it, you know, it starts going over this hill, it loses, it just loses contact with the road.
01:40
So it kind of just gets airborne.
01:47
And basically when it reaches this crest of the hill, okay? and again, i don't sure, well, it's a little bit drawn off to scale because, you know, the hill is kind of like the length of the vehicle.
02:01
So i'm not sure what they mean by it reaches the crest of the hill.
02:05
I guess by the time that, you know, maybe one tire is here, one tire is here.
02:11
So the whole vehicle is going over...
