Answer:
Her average speed is 5 miles per hour.
Explanation:
Average speed is the ratio of total distance travelled in particular time.
The park's pond is 0.5 miles around.
She can swim 20 laps, it means she can swim total = 20 × 0.5
= 10 miles.
Time taken by her to complete the track = 2 hour
Now, Average speed =
=
= 5 miles/hour.

Because of friction and air resistance, every moving object will eventually come to rest unless a continuous net force is applied to it.
<h3>What is friction?</h3>
Friction is the opposition offered to motion of a body over another body.
Friction can either be:
- Solid friction as in friction in solids
- Fluid friction as in air resistance
The law of inertia states that an object will remain in its state of rest or state of motion in a straight line unless acted upon by an external force.
However, due to friction and air resistance, every moving object will eventually come to rest unless a continuous net force is applied to it.
In conclusion, moving objects come to rest because of friction and air resistance.

The size of the forces between you and the planet you're on is
your weight on that planet.
Don't forget that you pull the planet with a force equal to the force
that the planet pulls on you. Your weight on Earth is the same as
the Earth's weight on you !
