In a physics problem where the pulley and the inclined surface are frictionless, how does this affect the analysis of forces and motion?
A) The frictionless nature of the pulley and inclined surface means that only gravitational forces need to be considered, and friction forces do not affect the system's behavior.
B) The frictionless nature of the pulley and inclined surface introduces additional forces that must be calculated to understand the motion.
C) The frictionless nature of the pulley and inclined surface means that tension in the rope and normal force on the inclined surface need to be ignored.
D) The frictionless nature simplifies calculations, as it allows us to focus solely on the components of gravitational force and tension in the rope.
