A1.0 104 kg spacecraft is traveling through space with a speed of 1200 m/s relative to earth. a thruster fires for 2.0 min, exerting a continuous force of 25 kn on the spacecraft in a direction opposite the spacecraft’s motion. calculate the initial momentum and the final momentum of the spacecraft.

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.
