An industrial electromagnet can be modeled as an RL circuit, while it is being energized with a voltage source. If the inductance is 10 H and the wire windings contain 3 Ī© of resistance, how long does it take a constant applied voltage to energize the electromagnet to within 90% of its ļ¬nal value (that is, the current equals 90% of its asymptotic value)?

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle Ī± 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 hamiltonās equations (canonical equations) of motion.
