Answer :
Final answer:
To determine how far downstream a sailboat will be when reaching the opposite side of the river with a crosswind, information about the boat's velocity, crosswind velocity, and river width are needed, which are not provided in the question. Therefore the correct answer is d.
Explanation:
Relative motion in physics refers to the motion of an object with respect to another object or reference frame. It is the study of how the motion of one object appears when observed from a different frame of reference. Relative motion is a fundamental concept in physics and is crucial for understanding the dynamics of objects in different situations.
To determine how far downstream the boat will be, we must know the velocity of the crosswind, the velocity of the boat in still water, and the width of the river. Without these pieces of information, it is impossible to calculate the downstream distance. Physics problems involving relative motion often require multiple given values to solve for a specific quantity.
Understanding relative motion is essential for analyzing the dynamics of objects in different reference frames and for developing accurate models of physical phenomena. It allows scientists and engineers to predict and explain the behavior of systems under various conditions and to design technologies that operate effectively in different environments. The correct answer is (d) Not enough information provided.
