The average speed of the tennis ball is 3 m/s.
<h3 /><h3 /><h3>What is average speed?</h3>
Average speed can be defined as the ratio of the total distance to the total time covered by the body. The S.I unit of average speed is m/s.
To calculate the formula below.
Formula:
- S = d/t............... Equation 1
Where:
- S = Average speed of the ball
- d = Total Distance
- t = Total time.
From the question,
Given:
- d = 18 meters
- t = 6 seconds
Substitute these values into equation 1
Hence, The average speed of the tennis ball is 3 m/s.

Answer:
True.
Explanation:
The kinetic energy and potential energy are equal when an objects falls as its potential energy is converted into kinetic energy.
Answer:
False
Explanation:
No. The buoyant force on an object is the portion of its weight that appears to vanish
when the object is in any fluid (could be either a liquid or a gas).
If the object happens to float in a particular fluid, then the buoyant force at that moment
is equal to the object's weight.
Notice that the buoyant force on an object will be different in different fluids.
