Problem

Three identical-looking ice pucks slide without friction on a horizontal surface. • Puck 1:

m = 0.20\,\text{kg},\; v = 8\,\text{m/s}

• Puck 2:

m = 0.40\,\text{kg},\; v = 4\,\text{m/s}

• Puck 3:

m = 0.15\,\text{kg},\; v = 12\,\text{m/s}

Which puck has the greatest magnitude of linear momentum? a)

\text{Puck 1}

\text{Puck 3}

\text{Puck 2}

\text{All three have equal momentum}
