Question 37

The initial velocity of an object is \(u = \begin{pmatrix} -5 \\ 3 \end{pmatrix} ms^{-1}\). If the acceleration of the object is \(a = \begin{pmatrix} 3 \\ -4 \end{pmatrix} ms^{-2}\) and it moved for 3 seconds, find the final velocity.

  • A.\(\begin{pmatrix} -14 \\ 15 \end{pmatrix} ms^{-1}\)
  • B.\(\begin{pmatrix} -2 \\ 1 \end{pmatrix} ms^{-1}\)
  • C.\(\begin{pmatrix} 4 \\ -9 \end{pmatrix} ms^{-1}\)
  • D.\(\begin{pmatrix} 14 \\ -9 \end{pmatrix} ms^{-1}\)
