A woman starts from her home at 9.00 am, walks with a speed of 5 km h-1 on a straight road up to her office 2.5 km away, stays at the office up to 5.00 pm, and returns home by an auto with a speed of 25 km h-1. Choose suitable scales and plot the x-t graph of her motion.
Answer:
Speed of the woman = 5 km/h
Distance between her office and home = 2.5 km
It is given that she
covers the same distance in the evening by an auto. Now, speed of the auto = 25 km/h
The suitable x-t graph
of the motion of the woman is shown in the given figure.
