Use the bohr quantization rules to calculate the energy levels for the harmonic oscillator, for which the energy is mw? 2m, that is, the force is mw^r. restrict yourself to circular orbits. what is the analog of the rydberg formula? show that the correspondence principle is satisfied for all values of the quantum number n used in quantizing the angular momentum.

The cheetah is considered the fastest running animal in the world. cheetahs can accelerate to a speed of 20.1 m/s in 2.50 s and can continue to accelerate to reach a top speed of 28.1 m/s. assume the acceleration is constant until the top speed is reached and is zero thereafter.1) starting from a crouched position, how long does it take a cheetah to reach its top speed? (express your answer to three significant figures.) s2) how far does it travel in that time? (express your answer to three significant figures.) m3) if a cheetah sees a rabbit 120 m away, how long will it take to reach the rabbit, assuming the rabbit does not move? (express your answer to three significant figures.)
