Question

A student is trying to determine the critical angle (0) at which block will slide down
an incline. She knows the coefficient of static friction between the incline and the
block is 0.53 and the coefficient of kinetic friction is 0.44. Neglect drag.
Hint: One way to solve the problem is to solve for all quantities in terms of m, e and
g (but not u), then use f= uN and a trig identity to solve for 0.
What is the critical angle?

Expert Solution

Step 1

We know that let the mass of the block is m and the gravity g and the plane incline angle is $θ$ . The coefficient of static friction between the incline and the blcok is $μ_{s} =$ 0.53 and the coefficient of kinetic friction is $μ_{k} =$ 0.44

The figure shown in the figure the angle $θ$ is the critical angle at which block will slide down an incline.
