Answer:
The speed of the proton is 4059.39 m/s
Explanation:
The centripetal force on the particle is given by;
The magnetic force on the particle is given by;
The centripetal force on the particle must equal the magnetic force on the particle, for the particle to remain in the circular path.
where;
r is the radius of the circular path moved by both electron and proton;
⇒For electron;
⇒For proton
The speed of the proton is given by;
Therefore, the speed of the proton is 4059.39 m/s
Explanation:
I assume the acceleration calculated in part (b) is the 3.33 m/s² from your other question.
Use Newton's second law to find the total force:
F = ma
F = (60,000 kg) (3.33 m/s²)
F = 200,000 N
Since there are 2 engines, the thrust from each is half of this:
F = 100,000 N
In reality, there are forces other than thrust. There are also drag forces (rolling friction and air resistance).
From Newton's second law, if we increase the mass and keep the force the same, the acceleration decreases. So it would take longer to reach the take-off speed.
that would be given by

@ representing coefficient of kinetic friction.
thus 19.5/51.7 = 0.377
