Question

7. Katie and her best friend liam play tennis every saturday morning. When katie serves the ball to liam, it travels 9.5 meters south in 2.1 seconds. What is the velocity of the tennis ball

Answer 1

The velocity of the tennis ball is 4.52 m/s.

Step-by-step explanation:

Given that,

The distance covered by ball, d = 9.5 meters (due south)

Time, t = 2.1 sec

Let v is the velocity of the tennis ball. We know that the velocity of an object is given by the total distance covered divided by total time taken. It is given by :

`v=(d)/(t)\\\\v=(9.5\ m)/(2.1\ s)\\\\v=4.52\ m/s`

So, the velocity of the tennis ball is 4.52 m/s. Hence, this is the required solution.
