Question

a hiker walks 11km due north from camp and then turns and walks 11 km due east. What is the approximate displacement of the hiker from the camp?

Answer 1

Answer:

$d=11\sqrt2\ km$

Explanation:

Given that,

Displacement in North = 11 km

Displacement in East = 11 km

We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :

$d=\sqrt{11^2+11^2}\\\\= 11\sqrt2\ km$

Hence, the approximate displacement of the hiker from the camp is $11\sqrt2\ km$.
