Consider a mass m moving in a frictionless plane that slopes at an angle α with the horizontal. write down the lagrangian in terms of coordinates x, measured horizontally across the slope, and y, measured down the slope. (treat the system as two-dimensional, but include the gravitational potential energy.) find the two lagrange equations and show that they are what you should have expected.

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
