Problem

Two particles are moving along the

x

-axis. Particle 1 starts from

x=-10\ \text{m}

with velocity

4\ \text{m s}^{-1}

along the negative

x

-direction and acceleration

2\ \text{m s}^{-2}

along the positive

x

-direction. Particle 2 starts from

x=+2\ \text{m}

with velocity

6\ \text{m s}^{-1}

along the positive

x

-direction and acceleration

2\ \text{m s}^{-2}

along the negative

x

-direction. Both start simultaneously. (a) Find the time when they collide. (b) Find the

x

-coordinate where they collide.
