You also arrested me on the suspicion of art theft. I profess innocence, claiming that I forged a copy of the egg, and so I can’t be accused of stealing a copy that I made. How do you determine whether the egg is a copy or a real work of art? You know that the real Fabergé Egg is mostly hollow, while the “fake” egg may not be. You can model the egg as a cylindrical object (because modeling a real egg is complex), and roll it down an inclined plane. Measuring its velocity at the bottom of the inclined plane will allow you calculate the moment of inertia of the egg, which you can compare to the moments of inertia for a solid cylinder (a disk) and for a hollow cylinder (a hoop). You perform the experiment using a ramp 0.5 m high at one end. You measure the mass of the egg at 400 g and its maximum radius at 9 mm. After several trials, you determine the average velocity of the egg at the bottom of the ramp is 2.56 m/s. Am I going down for art theft?
Suppose that, while lying on a beach near the equator watching the Sun set over a calm ocean, you start a stopwatch just as the top of the Sun disappears. You then stand, elevating your eyes by a height H = 1.70 m, and stop the watch when the top of the Sun again disappears. If the elapsed time is t = 11.1 s, what is the radius r of Earth?

- Two toy racecars race along a circular race track. Both cars start at the 3-o'clock position and travel in the CCW direction. Let t represent the number of seconds since the start of the race. Imagine angles with terminal rays that pass through each car as it moves. Car A is constantly 4.5 feet from the center of the race track and travels a constant speed. The angle with a terminal ray passing through Car A sweeps out 2.5 radians per second. Write an expression (in terms of t) that represents Car A's vertical distance above the center of the race track in feet.arrow_forwardFind the distance between the Earth and the planet Venus at the point of maximum elongation B ?!
