question 71

Multiple Choice

The position vector of a particle is r(t) . Find the requested vector.
- $\text { The acceleration at } t = 1 \text { for } r ( t ) = \left( 3 t - 3 t ^ { 4 } \right) \mathbf { i } + ( 3 - t ) \mathbf { j } + \left( 4 t ^ { 2 } - 4 t \right) k$

• A) a(1) = -36i - j + 8k
• B) a(1) = -9i + 8k
• C) a(1) = 36i + 8k
• D) a(1) = -36i + 8k
