Many airports have "moving sidewalks" or "moving walkways"-slow-moving conveyors which transport people across distances. A woman in an airport stands on a moving sidewalk with a speed $v_1$ and a length $L$. A man on the same moving sidewalk walks with a speed $v_2$ relative to the sidewalk (and in the same direction as the moving sidewalk's motion). (a) How long does it take the woman to travel the length of the moving sidewalk? (Use any variable or symbol stated above as necessary.) $\Delta t_{woman}$ = (b) How long does it take the man to travel the same distance? (Use any variable or symbol stated above as necessary.) $\Delta t_{man}$ = (c) Next to the first moving sidewalk is a second one that is identical to it, but moves in the opposite direction at speed $v_1$. A child steps onto this second sidewalk at the same instant the man above steps onto the first one. At that instant, as described above, the man walks at speed $v_2$ relative to his sidewalk, but the child stands at rest relative to this second sidewalk. How long after stepping onto the moving sidewalk does the man pass the child? (Use any variable or symbol stated above as necessary.) $\Delta t_{man}$ = (d) What If? If, instead of standing at rest, the child begins walking toward the man with speed $v_3$ relative to his moving sidewalk, after what time interval does the man now pass the child? (Use any variable or symbol stated above as necessary.) $\Delta t_{man}$ =

Consider a list of integer places that is not empty and is referred to as inList. In accordance with the following line of reasoning, determine and output outList: Using the following principles, construct a sequence of numbers for each element in inarr, beginning with the one that is immediately to the left of the current element: • In the series, the current element is the number that comes first in the sequence. • Using the current number as a starting point, the following formula is used to generate the next number in the sequence: o Divide the current number by two to determine the next number in the sequence, provided that the current number is even. o For the next number in the sequence, if odd, multiply the current number by three and then add one. This will give you the next number in the sequence. o Continue performing the processes outlined above until the number 1 is produced. Using a C program, determine how many numbers are contained in each sequence that has been constructed. Next, add the appropriate identified counts to outList in the order that the elements appear in inList. Sample Input 10 100 Sample Output 7 26 Explanation: Input: 10 100 For 10: Sequence - 10, 5, 16, 8, 4, 2, 1 (Total count = 7) For 100: Sequence - 100, 50, 25, 76, 38, 19, 58, 29, 88, 44, 22, 11, 34, 17, 52, 26, 13, 40, 20, 10, 5, 16, 8, 4, 2, 1 (Total count = 26) Therefore, outList = 7 26
