Problem

A particle starts from the origin at

t = 0

with a velocity of

8.0\hat{j}

m/s 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 m, what are a. its

y

-coordinate b. its speed ?
