Problem

A particle starts from the origin at

t=0

with a velocity of

8.0\hat{j}\text{ m s}^{-1}

and moves in the

x

y

plane with a constant acceleration of

(4.0\hat{i}+2.0\hat{j})\text{ m s}^{-2}

. At the instant the particle's

x

-coordinate is

29\text{ m}

, find the following. (1) Its

y

-coordinate. (2) Its speed.
