Assume this year there will be 25,000 runners participating Boston Marathon. Assume the average performance of the runner will improve 5mins (220mins) with the same standard deviation (60mins), and the data will still be normally distributed. To finish as the first 500 runners, Dr. Hu needs to finish the Marathon in 280 mins 100 mins 340 min 160 mins

Texts: help please Question 3: [2 Points] Using Table 4.2 of GF2, determine the multiplicative inverses of 4D and 4E. Note: This is just a table look. No math is needed. Question 4: [2 Points] Using Table 4.3 of GF(2), determine the AES S-box substitutions of 5E and 5F. Note: This is just a table look. No math is needed. Question 5: [6 Points] You are given the following 128-bits expressed as Hexa characters as input to the AES ShiftRows sublayer (just for one round): E5C2D6A8B0C8F99C7B1F8E0682337485 Determine the 128-bit output as 32 Hexa characters. Hint: Refer to page 104 of the textbook. First, arrange the input data into a matrix of bytes. For example, the two characters "Hexa ES" become a single byte. This value, "E5", will go to the B cell of the matrix given below. Similarly, the next two characters in the input, "Hexa C2", become a single byte. This value, "C2", will go to the B cell of the matrix given above.

Two cars A of mass 1500 kg and B of mass 2000 kg are on converging paths and subsequently collide. They are moving on a horizontal surface and before the collision the angle between their paths is 60°. Before the collision the speeds of A and B are 10 m/s and 15 m/s respectively. Estimate the energy loss in the impact if the cars become entangled
