Problem

A mountaineer of weight

700\,\text{N}

uses two identical snowshoes, each

0.25\,\text{m}

wide. The snow can withstand a maximum pressure of

1.4\times10^{3}\,\text{Pa}

. For safety, the actual pressure must be kept

20\%

below this maximum. Assuming each shoe supports half the weight, calculate the minimum length of each snowshoe. (a)

2.50\,\text{m}

(b)

1.25\,\text{m}

(c)

0.83\,\text{m}

(d)

1.00\,\text{m}
