Question
A block of wood weighing 32 N is placed on a rough slope and a rope is
tied to it. The tension in the rope can be increased to 8 N before the block starts
to slide. A force of 4 N will keep the block moving at constant speed once it has
been set in motion. Determine the coefficients of static friction
- 1.1
- 7.8
- 0.99
- 0.25
The correct answer is: 0.25
