Problem

Four objects move along the

x

-axis. • Object A:

m = 2\,\text{kg},\; v = +1\,\text{m/s}

• Object B:

m = 1\,\text{kg},\; v = +4\,\text{m/s}

• Object C:

m = 3\,\text{kg},\; v = -2\,\text{m/s}

• Object D:

m = 0.5\,\text{kg},\; v = -6\,\text{m/s}

Rank the objects’ momenta from the most negative to the most positive. a) D, C, A, B b) C, A, D, B c) C, D, A, B d) C, D, B, A
