Part 2) A block with a mass of m = 0.410 kg is placed on a plane that can be tilted, as shown below. The coefficient of static friction between the block and the plane is 4, = 0.350, while the coefficient of kinetic friction between the block and the plane is Hk = 0.270. The angle between the inclined plane and the block is slowly increased. No additional force is applied to the block. m At what angle will the block start to slide down the plane?

Question 4 Which of the following best describes the directions of friction and normal force? Your answer: Friction is always horizontal and normal force is always vertical. Friction is always horizontal and normal force is always perpendicular to the surface. Friction is always parallel to the surface and nomal force is always vertical. Friction is always parallel to the surface and normal force is always perpendicular to the surface. There is no consistent pattem.
