c) Use Newton's Laws of Motion to determine the acceleration of the crate as it slides across the horizontal surface, and use kinematics to determine the horizontal distance, d, where the crate comes to rest. d) Calculate the work done by each force on the crate as it slides down the inclined plane, and use the Work-Kinetic Energy theorem to determine the speed of the crate at the bottom of the incline. Compare these new work/energy answers to your Newton's Laws/kinematics equations from part b above. e)Calculate the crate's change in kinetic energy as it slides across the horizontal surface. Use the Work-Energy Theorem to relate the crate's change in kinetic energy to the work done by each force to determine for the horizontal distance, d, where the crate comes to rest. Compare these new work/energy answers to your Newton's Laws/kinematics equations answers from part (c) above.

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).
