#16 its going to depend a lot on the weight of your car but 86 MPH is not nearly fast enough to maintain momentum to make that big a loop. Not even close

#11 I did the math on what they would cost from my local store, and left is $15ish and the right is closer to $83. Thin slices of salmon aren't cheap at $23 lb, and blueberries are $8 for the smallest clamshell, and don't get me started on the price of a soft white cheese starting at $34 lb.

#20 Legibly. Or it would be completely black.

"If only contacting the floor with the heel then yes.

An elephant's foot is 15-19 inches across, so assuming it's vaguely circular gives an area of at least 0.114m2 per foot. Elephants when walking depending on the gait will have 2/3 feet in contact with the floor - so that's at least 0.228m2 in contact with the floor. (Going for minimum area as this will give the highest pressure for the comparison)

6000lbs under Earth's gravity is a force of 26.7kN, which when divided by area for a pressure of ~117kPa - if it's just standing still this could actually be halved to approx 58kPa

If a 100lb woman (445N) is standing on only her heels (~1cm2 x 2) this is a pressure of 2,224kPa which is indeed about 20 times higher than the elephant on 2 feet.

However that's not really representative of how heels are worn, even the picture shown has the shoes in contact with at least 20x the area of the ground than just the heels"
