A 80 kg pilot flies a plane in a loop. At the top of the loop, where the plane is completely upside-down the pilot feels no forces from the seat or the seat belts. (The pilot is “weightless.”) If the plane’s speed is 150 m/s, what is the radius of the loop?

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

One object has a mass of 1 kg and another object has a mass of 3 kg. if the speeds are the same, which of the following is true about their kinetic energy?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
