Problem

Skater P of mass

40\,\text{kg}

and skater Q of mass

80\,\text{kg}

stand at rest on ice that offers a kinetic friction coefficient of

0.10

with their skates. They push apart and then glide until they come to rest. Taking

g=10\,\text{m/s}^2

, what is the ratio of the distances they travel before stopping,

d_P : d_Q

? a)

2:1

4:1

1:4

1:2
