Question

5. A crate has a mass of 42.0 kg. The coefficient of static friction between the surface and the crate is 0.422. The coefficient of kinetic friction between the surface and the crate is 0.3.44. If a person pushes the crate by pushing down at an angle of 24°, what is the minimum force it would take to get the crate moving and then keep it moving? Suppose instead a rope is tied to the box and it is pulled at an angle of 24° above horizontal, what minimum force is now required to start and to keep the crate moving?
