Question #263873

Compute the acceleration of the block sliding down a 20^o inclined plane if the coefficient of kinetic friction is 0.60.

Expert's answer

The block will be in motion if

"\\tan\\theta>\\mu"

In our case

"\\tan20^{\\circ}=0.36<0.6"

So, the block is at rest, and acceleration is zero.
