### Physics Problems #### Problem 1: Bob is walking along an abandoned railroad track. He starts walking when his position is \( r = 3.45 \, \text{m} \hat{i} \), and undergoes a displacement of \( \Delta r = - 10.2 \, \text{m} \hat{i} \). What is his final position? #### Problem 2: Bob is driving in his car, accelerating at a rate of \( 3.21 \, \text{m/s}^2 \). After 2.65 seconds he is traveling at \( 15.1 \, \text{m/s} \). a) What is his initial velocity? b) How far has he traveled in that time? --- #### Problem 3: Dr. Smeevenstein’s minions have been ordered to reconstruct the elevator in Smeevenco headquarters, as it is very important that science is moved from the basement test chambers to the production floor as efficiently as possible. The safety code dictates that the elevator cannot accelerate or decelerate any faster than \( 2.73 \, \text{m/s}^2 \), and cannot travel any faster than \( 15.0 \, \text{m/s} \). The total distance that must be traveled is 373 meters. a) What is the shortest time that the elevator can take from the bottom to the top? #### Problem 4: Jane is hang-gliding, flying northward at 12.0 m/s. Suddenly, a gust of wind blows to the east, accelerating the glider (and Jane!) for \( a_{\text{wind}} = 0.400 \, \text{m/s}^2 \). The wind gust lasts for 4 seconds. a) What is the magnitude and direction of Jane's displacement over these four seconds? --- ### Explanation of Graphs and Diagrams There are no graphs or diagrams present in the image.
