Q3 (5pt) A particle of mass m is attracted to a force center with the force of magnitude k/r2. Use the plane polar coordinates (r, ?) and the Hamiltonian method to find the equation of motion for r and ?.
A particle of mass m is released from rest a distance b from a fixed origin of force that attracts the particle according to the inverse square law: F(x)=-kx-2 Show that the time required for the particle to reach the origin is (mb311/2 ( 8k Hint: Treat this as a 1-D problem. Then just integrate. And integrate. And integrate some more!
# Problem 1 # Suppose a point-mass particle with mass, 'm', moving in a gravitational potential, 'U(r)', where 'r' is the distance from the center of the potential. A positional vector and momentum vector of a particle are vec r' and "vec p', respectively. (\vec means vector symbol.) Q1) An angular momentum vector vec J' is defined as vec J = \vec r x \vec p. Show that \vec J is conserved in such a gravitational potential U(r) which depends...
2. Consider a point particle of mass m undergoing a one-dimensional motion under the action of a force F(x) =-kx + az where k and ? are positive constants. Follow Example 3 in the lecture notes on Differential equations and discover an integral of motion I(x,v) - const for this mechanical system. Plot the integral curves (x, v) in phase space, by using the ContourPlot command in Mathematica to plot the lines of constant I(x,v). Set significance. (6 points)

A bead of mass m slides smoothly from point A to point B on a semicircular horizontal wire loop of radius R. It is attracted toward its starting point A by a force F directly proportional to its distance r from A (for instance, you can imagine an elastic string connecting m to A). What it reaches B the force toward A is Fo. Numerical values: Fo = 2 N, R = 20 cm, m = 500 g. Calculate the...
