A car is traveling up a 2% grade at 70 mi/h on good, wet pavement. The driver brakes to try to avoid hitting stopped traffic that is 250 ft ahead. The driver's reaction time is 0.5 s. At first, when the driver applies the brakes, a software flaw causes the antilock braking system to fail (brakes work in non-antilock mode with 80% efficiency), leaving 80 ft skid marks. After the 80 ft skid, the antilock brakes work with 100% efficiency. How fast will the driver be going when the stopped traffic is hit if the coefficient of rolling resistance is constant at 0.013? (Assume minimum theoretical stopping distance and ignore aerodynamic resistance.)

5. Given that the ASCII codes for 'A' through 'Z' are x41 through x5A; and the codes for 'a' through 'z' are x61 through x7A: What are the bit-mask and the logic operation (NOT the LC3 instruction) that would force a character stored in R0 to lower case - i. e. convert an upper-case character stored in R0 into lower case, and leave a lower case unchanged (so 'A' would become 'a', and 'a' would remain 'a').

Note: the LC-3 stores ASCII characters in the lower ("right-hand") byte of a 16-bit word, with the upper byte set to zero

C#: Arrays - Ask the user how many students names they want to store. You will create two parallel arrays (e. g. 2 arrays with the same size, the first array will hold all of the students first names and the second array will hold all of the students last names). Once the user has input all of the students first names last names, output all of the students names in the following format: Lastname, Firstname. You must use two separate loops, the first to store the values in the arrays and the second to output all of the names.
