Roger Federer is about to do his smooth, classical and effortless serve to Rafael Nadal in Australian open final. The ball isshot horizontally from a height of 3.0 m above the ground level of a tennis court, and 6.3 m from the net. The net is ofheight 0.9 m. Assume the ball only travels along the centreline of the court. The situation is shown in the Figure below.B0.9 mVA6.3 m3.0 m|▬▬▬stDetermine the horizontal velocity V₁ of the ball at point A so that it clears the net without touching it at point B. Alsocalculate the distances where the ball strikes the ground.Note: Show your workings for each part of the question. Provide your answer to 2 decimal places.
