Problem

A wooden block rests on two different rough planes, one inclined at

20^{\circ}

and the other at

35^{\circ}

to the horizontal. The coefficient of kinetic friction is the same for both planes,

\mu_k = 0.15

. On which plane will the block have the larger acceleration? Explain your answer in one or two sentences.
