Quantization of Energy 1. According to the classical theory of physics, the energy radiated by a blackbody
approaches infinity as the wavelength of the emitted light approaches zero.
a. Why was this considered a problem for classical physics?
b. Max Planck solved this problem in 1900. What was the key to the solution?
c. How does Planck's assumption solve the "ultraviolet catastrophe"?

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
