Consider a mass m moving in a frictionless plane that slopes at an angle a 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.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

The stopwatch used by a student to measure velocity of a pulse in a slinky was of least count 0.1 second. he stops the stopwatch when a pulse has made 3 journeys from one end to the other of the slinky. he finds the seconds hand to be at 52nd division. calculate the correct time noted by him.
