"Im gonna assume the loop is about 60m based on the height of the building next to it.
At the top of the circle, the two forces are mg and centripetal force. The two together equal ma (a being v2/r.) So mg + Fc = m(v2/r). Set Fc to 0 as you would have to have a centripetal force slightly above 0 to complete the loop. This gives us v2 = sqrt(gr). For a 60m loop (30m radius) v = 17.1m/s.
This is the speed at the TOP of the loop. Using conservation of energy, we can say that 1/2mv2 + mgh = 1/2mv2 (the first part is top of loop, second part is bottom of loop). Cancel m and plug in numbers.
You would have to travel 38.34m/s or 138kph (85.7mph) to make the loop."

#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.
