Final answer:
The angle at which Jack Frost pulls the rope with respect to the horizontal cannot be determined from the work value alone, without knowing the force applied or the distance the sled was pulled. Therefore, this seems to be a trick question, but if all the work was translated to horizontal motion, the angle would be 90 degrees.
Step-by-step explanation:
The question relates to the concept of work done in physics, particularly when it comes to motion on a frictionless surface. When Jack Frost pulls on a rope to give Cindy Lou Who a ride across an icy pond surface with no friction, he performs work on the sled. Since there's no mention of force or distance in the question, and given that physics problems of this nature typically require more information, we can infer that this is a trick or hypothetical question. In reality, the work done on the sled cannot be attributed to the angle of the rope unless one of two things is known: either the force he applied or the distance the sled was pulled. Without this information, the work done provides no clue about the angle to the horizontal. All we know is that if Jack Frost did 247 Joules of work on the sled, and assuming that the work was not wasted vertically, the most efficient transfer of energy would occur when the force is applied in the direction of the movement, which is the horizontal direction. Therefore, the answer would be D. 90 degrees, as this implies that all the work was directed horizontally, parallel to the motion of the sled.
