Question

A rubber toy duck is at rest on an inclined plane. When the angle of inclination of the plane is increased to 35.9o, the toy duck begins to slide down the incline. Then, when the angle is decreased to 30.9°, the speed of the toy duck is constant. What are the coefficients of
static and kinetic friction between the toy duck and the incline?

kinetic

Expert Solution

Step 1

$Initial angle of the incline (θ_{1}) = 35 . 9^{o} Initial speed of rubber toy (u) = 0 \frac{m}{s} New angle of incline (θ_{2}) = 30 . 9^{o} New speed of rubber toy (v) = c o n s \tan t Let the mass of rubber toy = m$
