A block of mass m = 5.8 kg is pulled up a = 25° incline as in the figure with a force of magnitude F = 32 N.
(a) Find the acceleration of the block if the incline is frictionless.
(b) Find the acceleration of the block if the coefficient of kinetic friction between the block and incline is 0.10.
A man exerts a horizontal force of 125 N on a crate with a mass of 30.0 kg.
(a) If the crate doesn’t move, what’s the magnitude of the static friction force?
(b) What is the minimum possible value of the coefficient of static friction between the crate and the floor?
