How long was the ice flow in the first tray?
After the ice melted, how was the sand in the first tray different from the sand in the second tray?
What was the sand depth in the first tray at the beginning of the experiment? What was the sand depth at the end? Answer these questions for the second tray.
Did erosion take place in either tray? Explain your answer.
How do you think the results would change if the trays were propped up two inches?

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.
