PLLL ANSWER FASSST :) There are 25 cowbirds and 25 chipping sparrows in a forest. Female cowbirds are parasites to other bird species like the chipping sparrows. If the cowbird population size suddenly decreased to 5, how would it affect the size of the chipping sparrow population? A. The chipping sparrow population would increase. B. The chipping sparrow population would decrease. C. The chipping sparrow population would go extinct. D. The chipping sparrow population would stay the same.

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.
