question 1

Multiple Choice

A tennis player wants to slam a serve at O so that the ball lands just inside the opposite corner of the court.What should the ratio $\frac { v _ { 0 y } } { v _ { 0 x } }$ be for the initial velocity $\overrightarrow { \mathbf { v } } _ { 0 }$ ? The time t = 0 is the time when the ball is hit by the racket.

• A)W/L
• B)L/W
• C) \(\frac { 1 } { 2 } g t ^ { 2 } / L\)
• D) \(\frac { 1 } { 2 } g t ^ { 2 } / W\)
• E) \(\frac { 1 } { 2 } g t ^ { 2 } / \sqrt { L ^ { 2 } + W ^ { 2 } }\)
