Question

A truck yravelling due north at 20 m/s turns west and travels at the same speed. the change in its velocity be_

Answer 1

initial velocity is

20i
final velocity is
20j
change in velocity =
$\sqrt{20 {}^{2} + 20 {}^{2} } = 20 \sqrt{2}$
mark brainliest please

Answer 2

$Initial Velocity = 20j$

$Final Velocity = 20i$

$Change in Velocity = 20j-20i$

$=\sqrt{20^2+20^2}$

$=20\sqrt{2}$ $m/s$
