Position in undamped free vibration is given by
where
also
it is given
substituting values we get
Answer:
The average acceleration of the ball during the collision with the wall is
Explanation:
<u>Known Data</u>
We will asume initial speed has a negative direction, , final speed has a positive direction, , and mass .
<u>Initial momentum</u>
<u>final momentum</u>
<u>Impulse</u>
<u>Average Force</u>
<u>Average acceleration</u>
, so .
Therefore,
Explanation:
Given that,
Charge 1,
Charge 2,
Distance between charges, r = 0.0209 m
1. The electric force is given by :
F = -492.95 N
2. Distance between two identical charges,
Electric force is given by :
Hence, this is the required solution.
The masses of the objects and how much distance there is between them
The conversion factor you use is 100 cm = 1 m.
You can divide 20 by 100 to get the answer.
20 cm/100 cm =.2 m
Hope this helped!
