What displacement must be added to the displacement $25\hat i - 6\hat j\,\,m$ to give a displacement of $7.0\, m$ pointing in the $X- $direction
What displacement must be added to the displacement $25\hat i - 6\hat j\,\,m$ to give a displacement of $7.0\, m$ pointing in the $X- $direction
$18\hat i - 6\hat j$
$32\hat i - 13\hat j$
$ - 18\hat i + 6\hat j$
$ - 25\hat i + 13\hat j$
What displacement must be added to the displacement $25\hat i - 6\hat j\,\,m$ to give a displacement of $7.0\, m$ pointing in the $X- $direction
Previous position $=25 \hat i - 6 \hat j $
New position $=7 \hat i+0 \hat k $
Displacement $=$ (New position) $-$ (old position) $=(7 \hat i+0 \hat j)-(25 \hat i-6 \hat j)=-18 \hat i+6 \hat j $
Required displacement $=-18 \hat i + 6 hat j $
