Aglider of mass 5.0 kg hits the end of a horizontal rail and bounces off with the same speed, in the opposite direction. the collision is elastic and takes place in a time interval of 0.2s, with an average force of 100n. what was the speed, in m/s, of the glider? a glider of mass 5.0 kg hits the end of a horizontal rail and bounces off with the same speed, in the opposite direction. the collision is elastic and takes place in a time interval of 0.2s, with an average force of 100n. what was the speed, in m/s, of the glider?

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.
