Problem

A particle moves from the point

(2.0\hat{i} + 4.0\hat{j})

m, at

t = 0

, with an initial velocity

(5.0\hat{i} + 4.0\hat{j})

\text{ms}^{-1}

. It is acted upon by a constant force which produces a constant acceleration

(4.0\hat{i} + 4.0\hat{j})

\text{ms}^{-2}

. What is the distance of the particle from the origin at time

2\text{s}

? (1) 15 m (2)

20\sqrt{2}

m (3) 5 m (4)

10\sqrt{2}
