The rest energy of an electron is 0.511 MeV. The rest energy of a proton is 938 MeV. Assume both particles have kinetic energies of 1.80 MeV. (a) Find the speed of the electron. c (b) Find the speed of the proton. c (c) By what factor does the speed of the electron exceed that of the proton? uelectron uproton = (d) Repeat the calculations in parts (a) through (c) assuming both particles have kinetic energies of 1 800 MeV. (Give the electron's speed to eight decimal places.) uelectron = c uproton = c uelectron uproton =
A ball is thrown straight up from a height of 1.56m above the ground and reaches a maximum height of 8.35m before falling to the ground. What the calls total time in the air
The 150-lb man lies against lies against the cushion for which the coefficient of static friction is 0.5. Determine the resultant normal and frictional forces the cushion exerts on him if, due to rotation about the z axis, he has a constant speed v =..
I am working on a project where we need to find an optimal transfer for a spacecraft from LEO to the L4 LaGrange point in the Earth-Moon system. In order to calculate the delta V for the arrival at the LaGrange point, we need to know the "veloci..
