3 slices of a partially eaten 12-inch pizza are shown above. The CM of the entire uneaten pizza is cm = - 1.4 in. and yox= - 1.4 in, as shown.
(a) Assuming that each remaining slice is identical, find the CM of each slice. Choose the origin as shown above.
Starting with the slice in Q2 and going cow give the 3 CM's in the (x, y) format.
HINT: By symmetry, the positions of the CM of each slice must be the same distances x and y from the middle of the
pizza.
(b) Is the crust of the pizza stuffed with cheese? Prove your answer.

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?
