A world-class tennis player can serve a tennis ball at 110 mi/h (about 49 m/s ). The length of a tennis court is 78 ft . Approximately how long does an opponent have to react from the instant the ball is served until the ball reaches the opponent?
A) 1/10 S
B)1/3 S
C) 1/2 S
D)1 S
Homework Answers
The speed of the tennis ball is
Converting it to ft/s, we get
The length of the court is
So, the time taken by the ball to reach the opponent is
So the correct option is
C) 1/2 S.
