Answer» N 1:A block SLIDES without friction down a fixed, inclined plane with θ=30°. What is block acceleration? Question 2:If coefficient of static friction between block and plane 0.4, at what angle will the block start sliding if it is initially at rest. Solutions:1. Let the acceleration be a :2. Now, in case of equilibrium conditions, the frictional force will be EQUAL and OPPOSITE to the PULLING force:So, at this angle , the block will start moving.
