What is the x-t (position-time) graph of a woman's motion if she starts from her home at 9.00 am, walks with a speed of 5 km/h to her office 2.5 km away, stays at the office until 5.00 pm, and returns home by an auto with a speed of 25 km/h?

Options

  1. AA straight line sloping upward from 9.00 am to 5.00 pm, representing her walk to the office, and then a horizo
  2. BA straight line sloping upward from 9.00 am to 5.00 pm, representing her walk to the office, followed by a hor
  3. CA horizontal line from 9.00 am to 5.00 pm, representing her stay at the office, followed by a straight line sl
  4. DA straight line sloping upward from 9.00 am to 5.00 pm, representing her walk to the office, and then a horizo

Correct answer

A. A straight line sloping upward from 9.00 am to 5.00 pm, representing her walk to the office, and then a horizo

Step-by-step solution

Correct Option is : (A) A straight line sloping upward from 9.00 am to 5.00 pm, representing her walk to the office, and then a horizontal line from 5.00 pm onwards, representing her stay at the office, followed by a straight line sloping downward indicating her return by auto.
