Question 13 A person going for a walk follows the red-colored path shown in the figure below. The total trip consists of three straight-line paths: d1 =100 m, d2 = 200 m, d3 = 200 m. At the end of the walk, what is the person's resultant displacement that is measured from the starting point in units of m?

Just as the man begins to walk, Not answered another train (train-B) starts passing by in the opposite direction with a speed of VB = 10 km/h. If the length of train-A is 90 m, Points out of how long does it take (in units of s) until it completely passes train-B as measured by the man. 5.00 Flag time length question VA train-A train-B Vm VB O a. 90.00 s O b. 7.50 s O c. 45.00 s O d. 18.00 s O e. 8.57 s
