Question

A ship moves due north at 100kmh on a river flowing due east at 25km Calculate the magnitude of the resultant velocity of the ship.​

Answer 1

Answer: 103.0776 km/hr approximately

===================================================

Work Shown:

Use the pythagorean theorem.

a^2 + b^2 = c^2

c = sqrt(a^2 + b^2)

c = sqrt(100^2 + 25^2)

c = 103.077640640441

c = 103.0776

This result is approximate. Round however you need to.
