The drunkard will fall into the pit after 29s. After taking 5 steps forward and 3 steps backward in 8 seconds, the individual is 2 meters distant from his starting position.
It can be written as:
X = 5-3=2 m in 8 sec
He will be 6 m distant from his starting place after 24 seconds.
He advances another 5 m before falling into a pit 11 m away from his starting point.
Total time T = 24 + 5 = 29 sec.
Distance and Displacement
Distance and displacement are two quantities that seem to mean the same thing, but have very different definitions and meanings.
- Distance is a scalar quantity that describes "how much ground an object has covered in its travels."
- Displacement is a vector quantity that expresses "how much an object is displaced". This is the global change in the object's position.
Distance is the total distance traveled by the body over a period of time.
Summary:
A drunkard is walking along a straight road. He takes 5 steps forward and 3 steps backward and so on. Each step is 1 m long and takes 1 s. There is a pit on the road 11 m away from the starting point. The drunkard will fall into the pit after?
