Problem

Particle 1 is projected from the ground, taken as the origin, at

t=0

with velocity

(30\hat{i}+30\hat{j})\,\mathrm{m\,s^{-1}}

. Particle 2 is projected from

(130\,\mathrm{m},75\,\mathrm{m})

t=1\,\mathrm{s}

with velocity

(-20\hat{i}+20\hat{j})\,\mathrm{m\,s^{-1}}

. Taking

\hat{j}

vertically upward and

\hat{i}

horizontal, match the following columns at

t=2\,\mathrm{s}
