Answer

(a) The belt exerts a static frictional force on an apple. (b) $\mu_s = 0.40$

Work Step by Step

(a) Since the apples do not slide on the conveyor belt, the belt exerts a static frictional force on an apple. (b) We can find the coefficient of static friction: $F_N~\mu_s = 0.40~N$ $\mu_s = \frac{0.40~N}{F_N}$ $\mu_s = \frac{0.40~N}{1.0~N}$ $\mu_s = 0.40$
