2 Two small smooth spheres \( A \) and \( B \), of equal radii and of masses \( k m \mathrm{~kg} \) and \( m \mathrm{~kg} \) respectively, where \( k>1 \), are free to move on a smooth horizontal plane. \( A \) is moving towards \( B \) with speed \( 6 \mathrm{~ms}^{-1} \) and \( B \) is moving towards \( A \) with speed \( 2 \mathrm{~ms}^{-1} \). After the collision \( A \) and \( B \) coalesce and move with speed \( 4 \mathrm{~m} \mathrm{~s}^{-1} \). (a) Find \( k \). [3] (b) Find, in terms of \( m \), the loss of kinetic energy due to the collision. [2]

3. Download the Gaussian.txt found on Canvas and put it in the same directory as your code. Load the values from the file using numpy.loadtxt() Compute the following the sum, length, mean of all the values in the file. Then compute root mean square deviation (RMSD) $RMSD = \sqrt{\frac{\sum_{i=0}^{i=N}(mean-values[i])^2}{N}}$ Since the values in the Gaussian.txt is drawn from a Gaussian distribution. The mean and RMSD should be almost the same as a Gaussian centered at 10 and with a sigma of 2.

Assume the following definition for one-way function: A function f: A?B is a one-way function, if f(x) is "easy" to compute with the current technology, and the inverse will take hours (or more) to compute with the current technology. Which of the following are one-way functions? Select all that apply. Question 2 options: f(x) = x³ mod 55, for all x ? {1,...,54}. f(x) = x³ + 1 for all real numbers x. f(x) = x³ mod n, for all x ? {1,..., n-1}, where n is the product of two primes of 2054 bit-length each. f(x) = x³ mod n, for all x ? {1,..., n-1}, where n is the product of two primes of 32 bit-length each.
