A boy moves 24m towards south and and then 7m towards east.What is the distance travelled by body also find its displacement. |
|
Answer» e he travelled = 24+7 = 31mdisplacement is the shortest distancewhen we draw DIAGRAM we get a TRIANGLE(RIGHT angled) and the hypotenuse will be the displacement. so, by pythagoras theoremso hyp² = 24² + 7² hyp = √576+49 hyp = √625 hyp = 25so the displacement = 25M |
