Question

A space bus is carrying student travelling along the positive x axis has a displacement of 6km and 2hrs as it passes traffic officer ...1/2hrs after the space bus passed the officer, he observed that a security dog is running 500m in the same direction of the space bus. What are the coordinates of the traffic officer as measured by the runing dog

Answer 1

As per the question

Speed of the traffic bus = $\dfrac{6}{2}=3km/hour$

After the 1/2 hour, it passes the traffic officer,

So the x co-ordinate of the traffic officer $=\dfrac{3}{2}km$

Now, before ending the journey, sniper dog was 500 m/sec behind the bus,

So, the co-ordinate of the traffic officer, measured by the dog$=-(5.5km -1.5km)=-4km$
