Am = } $(w). cos(mkr)dx Bm= f(x) = sin(mkr)dx - Given the periodic quadratic periodic function f(x) = G) "for - <x< . Calculate Ag. There is a figure below that you should be able to see. You may (may not) need: Jup.sin(u)du = (2-u?)cos(u) +2usin(u) /v2.cos(u)du = 2ucos(u)+(u2–2)sin(u) -N2 0
du 2. Potential energy is defined so that the force is the negative derivative of the potential energy associated with it: F = - (This means that U = - SF dr, if you have learned integrals in your calculus class.) dr. See if you can guess the potential energy U that goes with Newton's universal gravitational force: F, = -G M3M2. The negative sign here indicates that it's an attractive force. If you know how to integrate, do that...
The potential energy is given by U(X) = 3xe^-x a) Determine the force b) Is the force conservative? Justify your answer
The potential energy of an object constrained to the x-axis is given by U(x) = 3x^2 - 2x^3. If x = 2.0 m, determine the force F(x) associated with this potential-energy function. Your Answer: Answer units
Consider the following boundary value problem: du du dx dx u=-e* sin(x) Discretize the ODE using backward second-order accurate scheme for both derivatives. The second order finite accuracy difference for the derivatives are given by: 2h (3)-1(1,2)-45 (7.1)+31(x) 8 (*)== (4.5) +41 (1.2) -51 (3.1) +2f (x) h?
so I know the answer to a) is U(x) = 4e(-2x) + 1
b) and the force is conservative, but how can I prove the force
is conservative
