Answer:
Time period of ball's motion is 4.6 s
Frequency of ball's motion is 0.22 Hz
Explanation:
In this problem, Time period is define as the time taken by the ball to come back to its original position.
Let A be the player who first hits the ball towards the player B. We know that ball takes 2.3 s to travel from player A to player B. It takes same time to come back to player A from player B. Thus,
Time period of ball's motion = 2 x 2.3 s = 4.6 s
Frequency is defined as the occurrence of any event per unit time. In this case, the frequency of the ball's motion is given by :
Frequency = [tex]\frac{1}{Time\ Period}[/tex]
Frequency = [tex]\frac{1}{4.6}[/tex] = 0.22 Hz
