Question

A pilot in an air Niugini travelling at 400km/h north sees an airlines aeroplane directly in front of her travelling south at 300 km/h. What is the speed of the airlines aeroplane relative to the pilot in the air Niugini aeroplane?​

Answer 1

To find:-

• The relative velocity.

Answer:-

We are here given that two aeroplanes are travelling in opposite directions to each other that is North and South .

Speed to pilot traveling towards north is ,

`\implies v_N = 400\ km/hr \\`

Speed of pilot traveling towards south is ,

`\implies v_S = 300\ km/hr \\`

Since they are traveling opposite directions the relative speed will be the sum of their speeds that is ,

`\implies v_(relative) = 300km/hr + 400 km/hr \\`

`\implies \underline{\underline{ v_(relative)= 700km/hr}} \\`

Hence the relative speed is 700km/hr .

and we are done!
