Solve the following questions:
a) A car travels along a straight road 100m east and then 50m west. Find the distance and displacement of the car
b) A worker covers a distance of 40km from his house to his place of work and 10km towards his house back. Then the displacement covered by the worker in the whole trip is?
Dear Student
a)
A car travels along a straight road 100m east and then 50m west
So total distance = Distance travelled along east side + Distance travelled along west side
Total distance = 100 + 50 = 150 m
Distance is scalar quantity so we didn't considered direction during calculation.
Total displacement = Distance travelled along east side - Distance travelled along west side ( -ve sign as east and west direction is opposite to each other)
Total Displacement = 100 - 50 = 50 m
b)
A worker covers a distance of 40km from his house to his place of work and 10km towards his house back.
Then the displacement covered by the worker = Distance travelled from house to work - Distance travelled back to house
Displacement = 40 - 10 = 30 Km
