Dos bolas, de masas ma = 40 g y mb =60 g, esta? n suspendidas como se observa en la figura. la bola ma? s ligera se jala en un a? ngulo de 60° con respecto a la vertical y se libera. a) ? cua? l es la velocidad de la bola ma? s ligera antes del impacto? b) ? cua? l es la velocidad de cada bola despue? s de la colisio? n ela? stica? c) ? cua? l sera? la altura ma? xima de cada bola despue? s de la colisio? n ela? stica?

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.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
