Question:
A particle starts from the origin goes along the X-axis to the point (20m, 0) and th32en returns along the same line to the point (-20m, 0). Find the distance and displacement of the particle during the trip.
Solution:
Distance travelled $=20+40=60 \mathrm{~m}$
Displacement $=20 \mathrm{~m}$ in the negative direction
