Question

an airplane flies 400m from North and then flies 300 m south and then flies 1200m upwards then net displacement is?

Answer 1

The net displace is hypotenuse of triangle ,in which 1st side =400-300=100m and 2nd side=1200m

by applying pythagorous theorem we get,
${h}^{2} = {100}^{2} + {1200}^{2}$
${h}^{2} = 10000 + 1440000$
${h}^ = \sqrt{1450000}$
$h = 1024(approx)$

Answer 2

Answer:

Explanation:

Net displacement is √100^2+1200^2

1204approx
