This is a top -down view of the situation that was described in the problem.
00:07
We've got our pizza box, and it's going to be kind of wedged up against the windscreen and up against the steering wheel like this.
00:17
And it's said in the problem that we still need to worry about it sliding to the right and sliding toward the seat.
00:24
So the question is, do we need to worry about it sliding more when we turn left or turn right? in other words, in which case is it going to slide to the right? and for this, this will happen.
00:38
It'll slide to the right when we turn our car to the left.
00:43
And the reason for this is when we turn our car to the left, the inertia of the pizza box wants to keep it moving straight, straight ahead.
00:54
And so the car is going to be turning out from under the pizza box.
01:00
And so we need to rely on the coefficient of friction.
01:04
We need to rely on the friction between the pizza box and the dash to keep it in place, to pull it to the left with the car.
01:13
So if we turn too quickly, the car is going to slide out from under the pizza box...
