Suppose that a bee is flying around and at time t=0, the bee spots a delicious flower and starts buzzing around it excitedly. As the bee buzzes around, let s(t) give the height (in centimeters) of the bee above or below the flower at time t (measured in seconds). For instance, s(0)=0.981, which means that at time t=0, the bee is 0.981 cm above the flower. a) Compute the average velocity of the bee on the following time intervals. [0.5,1] [1,1.5] [0.75,1.25] [0.9,1] [1,1.1] [0.95,1.05] [0.99,1] [1,1.01] [0.995,1.005] b) Of the 9 average velocities computed, which do you think gives the best estimate of the instantaneous velocity of the bee at time t=1? c) Compute an even better estimate of the instantaneous velocity of the bee at time t=1. d) Estimate the instantaneous velocity of the bee at t=4. What does this value tell you about the movement of the bee at the instant t=4?

2. (12) The energy level diagram of the element adamantium is shown at right. You shine light through a sample of liquid adamantium and measure the light you see on the other side of the sample, exactly like what you did in lab. The spectrophotometer you are using accurately measures all the wavelengths from 300 to 900 nm. In your experiment you shine light with wavelengths from 300 to 700nm through the sample (shown below). Draw the spectrum you see on the other side of the sample and explain any differences between the spectrum you see on the other side and the light you originally shone on the material. Spectrum of light shone on material -6.625 eV -8.246 eV -8.500 eV -10.500 eV Number of photons 300 400 500 600 700 800 900 Wavelength (nm)

Observing that $x_c(t) = Re(\bar{x}(t)) = \frac{\bar{x}(t) + \bar{x}^*(t)}{2}$, show that $X_c(f) = \frac{X(f) + X^*(-f)}{2}$. Observing that $x_s(t) = Im(\bar{x}(t)) = \frac{\bar{x}(t) - \bar{x}^*(t)}{2j}$, derive a relation between $X_s(f)$ and $\bar{X}(f)$.
