Question

one of the rectangular component of velocity of 60m/s is 30m/s .find the other component

Answer 1

the other component is
$\sqrt{60 {}^{2} - 30 {}^{2} } = \sqrt{3600 - 900} = \sqrt{2700}$
=30√3

Answer 2

Answer:

The other component of velocity is 51.96m/s

Explanation:

Given that,

The Resultant velocity is 60m/s

The rectangular component of velocity is 30m/s

The other component of Velocity can be found using resolution of vectors as follows

$V = \sqrt{V_x {}^{2} + V _{y} {^{2} } } \\ V {}^{2} = {V_x {}^{2} + V _{y} {^{2} } }$

Substituting the known values we get

$60 {}^{2} = 30 {}^{2} + V _{y} {}^{2} \\ = > V _{y} = \sqrt{60 {}^{2} - 30 {}^{2} } = \sqrt{2700} \\ = 51.96ms {}^{ - 1}$

Therefore,the other component of velocity is 51.96m/s
