Question
10. A 10 kg crate of delectable cupcakes (with rainbow sprinkles, of course)
is being held at rest at the top of a frictionless INCLINED PLANE 8.0 m
long, making an angle of 30° with the horizontal. The crate is then
released from this position, slides down the frictionless inclined plane,
and encounters a HORIZONTAL floor. The coefficient of kinetic friction
8 m
between the crate and the floor is 0.400. The crate of cupcakes comes
to rest at a distance d from the bottom of the inclined plane, as shown.
30°
a. Draw two free-body diagrams: one for the crate sliding down the inclined plane, and one for the crate
sliding across the horizontal surface (before it comes to rest).
