Aproton in a synchrotron is moving in a circle of radius 1 km and increasing its speed by v(t) = c1 + c2 t 2 , where c1 = 2.0 × 105m/s, c2 = 105m/s3 .
(a) what is the proton’s total acceleration at t = 5.0 s?
(b) at what time does the expression for the velocity become unphysical?

a) 10^6 m/s^2

b) 7.39 s

Explanation:

Hello!

If the velocity is given by:

Then the acceleration is the derivative of the velocity with respect of time:

a)

Therefore the acceleration at t=5.0s is:

b)

The velocity will become unphysical when it equals the velocity of ligth (3x10^8 m/s)

3x10^8 m/s = 2x10^5 m/s + 10^5 m/s^3 t^2

Solving for t:

t^2 = 2998 s^2

t = 7.39 s

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
