Final answer:
It took the tennis ball 2 seconds to travel a distance of 5 meters at a speed of 2.5 m/s, which is an example of uniform motion in kinematics, a part of physics.
Step-by-step explanation:
If a tennis ball is traveling with a speed of 2.5 m/s and it travels a distance of 5 meters, we can find out how long it took to travel that distance by using the formula for speed, which is distance divided by time (speed = distance/time). We can rearrange this formula to solve for time (time = distance/speed).
So, using the given values:
Time = Distance/Speed
Time = 5 meters / 2.5 meters per second
Time = 2 seconds
Therefore, it took the tennis ball 2 seconds to travel a distance of 5 meters at a speed of 2.5 m/s. This is an example of uniform motion which is a key concept in kinematics, a branch of physics that deals with the motion of objects.
