Question

From a reference frame moving along the surface of the wall at speed v, the initial speed of the ball is A) $< | V - v |$ B) < {v²+ V²}^1/2. C) = {V²+ V²}^1/2. D) > {v²+ V²}^1/2.

Quizplus · Accepted Answer

The correct answer is C because the initial speed of the ball is the vector sum of the speed of the ball relative to the wall and the speed of the wall.
