Explanation:
Just a few things to remember:
-
# of neutrons = Mass number - # protons
-
Mass number = # protons + # neutrons
-
Atomic Number = # of protons
- # of electrons = # of protons - charge on the atom
-
Symbol - use the atomic number to find the element in the periodic table

<h3>
Answer:</h3>
Velocity is 1 m/s
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the kiddy train is 1000 kg
- Radius of the curve is 5.0 m
- Centripetal force is 2000 N
We are required to determine the maximum speed of the train.
- Centripetal force refers to the force experienced by an object in a circular motion towards the center of a circular path.
- It is calculated by the formula;
- , where m is the mass, v is the velocity and r is the radius of the circular path.
- Therefore, using the formula we can find the maximum speed.
Therefore, the maximum speed of the train is 1 m/s
