For this question you will need to use the remarkable fact that the function $e^x$ is its own derivative. That is, \frac{d}{dx}(e^x) = e^x$. \\ (e is just a constant, approximately 2.71828182846.) \\ Use that and the product rule to find the derivative of \\ $(2x^3 - 7x^{10})(6e^x - 3)$ \\ You do not need to expand out your answer.

1 The little prince lives on a spherical asteroid with a radius of R=4.0 meters and mass of M=7.0x105 kg (a) Find the escape speed required to escape the gravitational pull of the asteroid. You should derive the equation for the escape speed rather than recalling it from memory. W=d0 5 zF=ma g=9.8m1s 2 dt R=4m R mg M=7.Ox1Okg GM,mz U- 1g2 h-O1xh11 = H m/s (b) The little prince, who has a mass of m=35 kg, jumps off the asteroid with a speed of 1.2 m/s (which is faster than the escape speed) in a direction tangential to the asteroid's surface, as shown in the figure. If the asteroid initially is not rotating. what is its rotational period T (in hours) after the prince jumps off? You can approximate the prince as a point mass on the asteroid's surface, and the asteroid as 5 I=Emiriz 3=3 7m+N+3=I R 1.07x10-bs X 60s tR N T h a80000=33a.5+1.2 h7 1118670t=1.2 U=1.

The molybdenum-99 (Mo-99) ? technetium-99m (Tc-99m) ? technetium99 (Tc-99) decay series plays an important role in nuclear medicine, since it serves as the source of Tc-99m, the most widely used radionuclide for nuclear imaging tests. The series parent radionuclide Mo-99 decays through ?- decay with a half-life ($t_{1/2}$) Mo-99 = 66.0 hours into daughter radionuclide Tc-99m. Subsequently, the daughter Tc-99m decays through gamma emission with a half-life ($t_{1/2}$) Tc-99m = 6.02 hours to the granddaughter radionuclide Tc-99. The Tc-99 radionuclide has a much longer half-life [($t_{1/2}$) Tc-99 = 2.1×105 y] in comparison with Mo-99 and Tc-99m and decays through ?- decay to ruthenium-99 (Ru-99). Starting with a pure 10 mCi (0.37 GBq) Mo-99 source: (a) State or derive equations for activities of the Mo-99 parent and Tc-99m daughter as a function of time. (b) Calculate the characteristic time ($t_{max}$) Tc-99m at which the Tc-99m daughter radionuclide attains its maximum activity. (c) Determine the maximum activity of the Tc-99m radionuclide.
