Problem

A car of mass

1200\,\text{kg}

changes its velocity from

20\,\text{m/s}

eastward to

5\,\text{m/s}

westward in

0.20\,\text{s}

. Determine the impulse delivered to the car (magnitude and direction). a)

3.0\times10^{4}\,\text{kg m/s}

towards east b)

1.8\times10^{4}\,\text{kg m/s}

towards west c)

3.0\times10^{4}\,\text{kg m/s}

towards west d)

2.5\times10^{4}\,\text{kg m/s}

towards west
