Select the answer for each of the following questions, then press "Mark" at the bottom of the page to receive feedback.
A pen and paper may be required to assist in the answering of some questions.
Questions beginning with "cont...." follow on from the previous question.


1) Select from then list below the equation which represents application of vB = vA + vB/A.

One answer only.
   vBi = -3j + (wk) x (-4i + 3j)
   vBi = -3j + (wk) x (4i - 3j)
   vBi = -3j + (-wk) x (-4i + 3j)
   vBi = -3j + (-wk) x (4i - 3j)
   None of the above

2) Select from then list below the equation which represents application of vB = vA + vB/A.

One answer only.
   vBxi + vByj = 4i + (wk) x (-0.3cos30i + 0.3sin30j)
   vBxi + vByj = 4i + (-wk) x (-0.3cos30i + 0.3sin30j)
   vBxi + vByj = 4i + (wk) x (0.3cos30i + 0.3sin30j)
   vBxi + vByj = 4i + (-wk) x (0.3cos30i + 0.3sin30j)
   None of the above

3) Select from then list below the equation which represents application of vB = vA + vB/A.

One answer only.
   vBcos30i - vBsin30j = 10i + (wk) x (2cos20i - 2sin20j)
   vBsin30i - vBcos30j = 10i + (wk) x (2sin20i - 2cos20j)
   vBsin30i - vBcos30j = 10i + (wk) x (-2cos20i + 2sin20j)
   None of the above

4) Select from then list below the equation which represents application of vB = vA + vB/A.

One answer only.
   vBi = -3j + (wk) x (2i - 1j)
   vBi = -3j + (wk) x (-2i + 1j)
   -vBi = -3j + (wk) x (2i - 1j)
   -vBi = -3j + (wk) x (-2i + 1j)
   None of the above
