Q 3.4 A drunkard walking in a narrow lane takes 5 steps forward and 3 steps backward, followed again by 5 steps forward and 3 steps backward, and so on. Each step is 1 m long and requires 1 s. Plot the x-t graph of his motion. Determine graphically and otherwise how long the drunkard takes to fall in a pit 13 m away from the start.
time | 0 | 5 | 8 | 13 | 16 | 21 | 24 | 29 | 32 | 37 |
distance covered | 0 | 5 | 2 | 7 | 4 | 9 | 6 | 11 | 8 | 13 |
at time t= 37 dec the man falls in a pit at 13 meters from the start
