Tom the cat is chasing Jerry the mouse across a table surface 1.25 m high. Jerry steps out of the way at the last second, and Tom slides off the edge of the table at a speed of 5 m/s. Where will tom strike the floor?

What is his vertical velocity component just before he hits the floor?

Which is not a step in the rock cycle?

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.
