Two protons, initially 1.00 m apart, are shot directly towards each other, in a 1-dimensional motion
problem.
a. what is their minimum separation distance if their initial speed was 2.75 ร 104 mm/ss each?
b. what would the minimum separation distance be if they were electrons used in the same
experiment?
c. what will be the speeds be when they are far apart? (do this for both the protons and the
electrons.)
d. how much speed is needed to get the protons within 1 femtometer (10-15m) of each other
where the strong nuclear force can attract the two?

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle ฮฑ with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamiltonโs equations (canonical equations) of motion.
