What is the formula for maximum speed?
What is the maximum speed attained? This is the formula for distance, not speed! The formula for speed is simply v(0)t. 19.8*15.9= 314.82 m/s for the maximum speed.
What is the maximum speed of the photoelectrons emitted from this surface?

What is the maximum speed of an electron?
By measuring the energy required to change the velocity of electrons as they jumped from one atomic orbital to another while Earth rotated over a 12-hour period, they determined that the maximum speed of an electron – in theory, the speed of light, about 300 million meters per second – is the same in all directions to …
How do you find the maximum kinetic energy of an ejected electron?
The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe = hf − BE, where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.
How do you find the maximum speed of oscillation?
Because the sine function oscillates between –1 and +1, the maximum velocity is the amplitude times the angular frequency, v max = A ω v max = A ω . The maximum velocity occurs at the equilibrium position ( x = 0 ) when the mass is moving toward x = + A .
What is maximum velocity speed?
Max Velocity can be defined as the highest attainable velocity an object can reach, which is demonstrated by discontinuation of acceleration. Most athletes will reach Max Velocity between 20-50m.
What is the mass of photoelectron?
9.1×10−27kg.

What is the work function in eV of the surface?
From Wikipedia, the free encyclopedia. In solid-state physics, the work function (sometimes spelled workfunction) is the minimum thermodynamic work (i.e., energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the solid surface.
What is the formula to find speed of electron?
There is a way to estimate the speed of an electron in an atom. Its momentum is roughly (Planck’s constant) / (extent of orbital), and one divides by the electron’s mass to get its velocity. Or strictly speaking, (Lorentz factor) * (velocity), where (Lorentz factor) = (1 – (v/c)^2)^(-1/2) for velocity v.
What is the formula to calculate the speed of electron?
At speeds greater than the 1/10th of the speed of light, we must use the relativistic formula to find an electron’s velocity in an electric field: v rel = c 1 − 1 ( 1 + e V a m 0 c 2 ) 2 .
What is the formula for calculating the speed of an electron?
The electron starts from rest (near enough) so the kinetic energy gained is given by ½mv 2 where m is its mass and v is its speed. For an electron gun with a voltage between its cathode and anode of V = 100V the electron will have a speed of about v = 6 × 10 6 m/s.
How do you find the maximum kinetic energy of an object?
In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
How do you find maximum kinetic energy from potential energy?
Identify the spring’s maximum kinetic energy, at the equilibrium point, as equal to the initial potential energy. Calculate the kinetic energy at any other point of displacement, X, by subtracting the potential energy at that point from the initial potential energy: KE = (0.5)kx^2 – (0.5)kX^2.
