Chapter 12, Problem 5P
Your brother is opening a skateboard shop. He has created a sign for his shop made from a uniform material and in the shape shown in Figure P12.5. The shape of the sign represents one of the hills in the skateboard park he plans on building on land adjacent to the shop. The curve on the top of the sign is described by the function y = (x − 3)2/9. When the sign arrives in his shop, your brother wants to hang it from a single wire outside the shop. But he doesn’t know where on the sign to attach the wire so that the bottom edge of the sign will hang in a horizontal orientation. He asks for your help.

The bottom of the ruler is resting on the table. The place where the height measurement is taken is a little curved, so it is difficult to identify very precisely where the measurement should be taken. Also, it's a bit tricky to make sure the ruler is perfectly vertical (it might be leaning forward or backward a bit). When you take the measurement, you measure 12.9 mm. By moving the ruler a little, you are confident that the correct measurement is somewhere between 12.7 mm and 13.3 mm. Indicate the value that you will record in your logbook, as well as the uncertainty that you will attribute to it. Give your answers in mm. Warning: Keep at least 3 significant digits in your answers, even if it does not respect the rules of presentation of data in the laboratory.arrow_forwardYou use a millimeter ruler to measure the height of a rail curb.

- The bunchberry flower has the fastest-moving parts ever seen in a plant. Initially, the stamens are held by the petals in a bent position, storing energy like a coiled spring. As the petals release, the tips of the stamens fly up and quickly release a burst of pollen. Shown are the details of the motion. The tips of the stamens act like a catapult, flipping through a 60° angle; the times on the earlier photos show that this happens in just 0.30 ms. We can model a stamen tip as a 1.0-mm-long, 10 μg rigid rod with a 10 mg anther sac at one end and a pivot point at the opposite end. Though an oversimplification, we will model the motion by assuming the angular acceleration is constant throughout the motion.
