Answer:
Approximately .
Explanation:
The net force on the girl would be:
.
Under the assumptions, the net force on this girl would be equal to the tension force in the rope. All other forces on the girl would be balanced.
In other words, the tension force that the rope exerted on the girl would be . The girl would exert a reaction force on the rope at the same magnitude (
) in the opposite direction. This force would translate to a
force on the boy towards the girl.
Under similar assumptions, the net force on the boy would also be . Since the mass of the boy is
, the acceleration of the boy would be:
.
The rest energy of the proton will be 938 MeV. The rest energy is related to the rest mass of the proton.
<h3>What is rest energy?</h3>The rest energy is the rest mass times the square of the speed of light of a particle at rest in an inertial frame of reference.
The rest energy is found as;
Convert into the mega electron volt;
Hence, the rest energy of the proton will be 938 MeV
