Question 33

At time t t\,t seconds a particle has velocity v=4ti−3j\mathbf{v} = 4t\mathbf{i} - 3\mathbf{j}v=4ti−3j m s−1^{-1}−1.

Find the acceleration of the particle when t=2t = 2t=2.

Circle your answer.

A

4i4\mathbf{i}4i m s−2^{-2}−2

B

C

4i−3j4\mathbf{i} - 3\mathbf{j}4i−3j m s−2^{-2}−2

D

8i−3j8\mathbf{i} - 3\mathbf{j}8i−3j m s−2^{-2}−2
