Starting from rest, a proton falls through a potential difference of 1200 V. What speed does it acquire?

How much work must be done on an electron to accelerate it from rest to a speed of 0.939c? Number i Units

What is the speed of an electron that has been accelerated from rest through a potential difference (delta V) = +1000 V?  Use conservation of energy (delta K + delta U = 0).  Remember that delta U = q(deltaV)

In a television tube electrons are accelerated through a voltage of 5000 volts. What is the speed of the electrons assuming that they were initially at rest? (Since this is Physics 222, do not use special relativity to calculate the answer even though these speeds are a fraction of the speed of light.) Express your answer to the nearest km/s.

In a collider two protons are accelerated until they have kinetic energies of 1000 MeV (as seen in the lab). The pair is then split and brought around circular paths so that they are directed at each other. What speed of approach would one proton see the other as having? The mass of a proton is 1.673x10-27 kg (or 1.007276 u), and the rest mass energy of a proton is 938.3 MeV. (Speed is a scalar, so your answer will not need a direction.) K= 1000 MeV K = 1000 MeV

A constant electric field accelerates a proton from rest through a distance of 1.20 m to a speed of 1.53 ✕ 105 m/s.
