Question
A girl starting from her home went straight towards south for a distance of 10 m then turnedleft and walked for 10 m; she turned right again to walk for another 10 m and finally tookanother left turn and walked for 10 m to reach an ice cream shop. Draw a diagram to findher distance and displacement along with direction
Solution
Sure, here's how you can draw the diagram and find the distance and displacement:
Step 1: Draw a straight line representing 10m towards the south. Label the starting point as 'Home' and the end point as 'A'.
Step 2: From point 'A', draw a line to the left representing 10m. Label the end point as 'B'.
Step 3: From point 'B', draw a line upwards (which would be a right turn from her perspective) representing 10m. Label the end point as 'C'.
Step 4: From point 'C', draw a line to the left representing 10m. Label the end point as 'Ice cream shop'.
Now, to find the distance and displacement:
Distance: The total path covered by the girl. So, add up all the individual distances. That is, 10m (Home to A) + 10m (A to B) + 10m (B to C) + 10m (C to Ice cream shop) = 40m.
Displacement: The shortest distance from the initial to the final point. In this case, the girl ends up at the same latitude as her home but 20m to the west. So, her displacement is 20m towards the west.
