Question

<p>A ship is moving north at a constant speed of (15&#960;/180)-k&#160;m/s relative to the earth and is turning toward the west at a constant rate of (5&#960;/180)j degrees per second. Relative to the ships body-fixed coordinate system, the position, velocity and acceleration of a helicopter is:<br /><br />r(a/b)=420 i+ 236.2 j + 212 k meters <br />v(a/b)=-53.5 i +2 j+6.6k m/s<br />a(a/b)=.4i-.2j-13k m/s^2</p>
<p>Using&#160;&#937;=(5&#960;/180)j, Vb=15i, An=Vb*&#937;,Determine the helicopters velocity and acceleration relative to earth.</p>
