Work and Kinetic Energy – The Work-Energy Theorem Consider an object with an initial velocity ‘u’. A force F, applied on it displaces it through ‘s’, and accelerates it, changing its velocity to ‘v’. Its equation of motion can be written as: v2 –u2 = 2as Multiplying this ...
Because the mass m and speed v are given, the kinetic energy can be calculated from its definition as given in the equation KE=12mv2KE=12mv2. Solution The kinetic energy is given by KE=12mv2KE=12mv2. Entering known values gives KE = 0.5 (30.0 kg)(0.500 m/s)2, which yields KE ...
And as for finding the kinetic energy, I need to use the first equation, but apparently the units of Φ should not be in eV because that wouldn't make sense, how should I calculate KE_max then? Edit: ok I converted the hf into eV, then I got the answer 1.43 eV, which is the ...
