Una máquina de tiro al plato lanza los mismos con un ángulo de 45° respecto al suelo y a una velocidad inicial de 100 km/h. ¿Qué altura máxima alcanzarán los platos? ¿Cuál será su alcance máximo?

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α 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 hamilton’s equations (canonical equations) of motion.

Which notation is used to represent an alpha particle? a. b. c. d.
