Multiple Choice

A particle moves in the xy plane with a constant acceleration given by $\overrightarrow { \mathbf { a } } = - 4.0 \hat { \mathbf { j } } \mathrm { m } / \mathrm { s } ^ { 2 }$ .At t = 0,its position and velocity are 10 i? and $( - 2.0 \tilde { \mathbf { i } } + 8.0 \tilde { \mathbf { j } } ) \mathrm { m } / \mathrm { s }$ ,respectively.What is the distance from the origin to the particle at t = 2.0 s?

A) 6.4 m
B) 10 m
C) 8.9 m
D) 2.0 m
E) 6.2 m
