Text SolutionText solutionverified iconVerified

For simple harmonic motion (SHM) of a particle, acceleration (a) is given by the relation:
  
  is  angular frequency

is negative. The slope of the x-t plot is also negative. Therefore, both position and velocity are negative. However, using equation (i), acceleration of the particle will be positive.

x is positive. The slope of the x-t plot will also be positive. Therefore, both position and velocity are positive. However, using equation (i), acceleration of the particle comes to be negative. 

In this time interval, x is negative. The slope of the x-t plot is positive. Hence, the velocity comes to be positive. From equation (i), it can be inferred that the acceleration of the particle will be positive.

32+1+4+3=10 pts + 1 bonus pt. In this problem, we will derive the Generalized ERF formula. Consider a polynomial P of degree k which has a repeated root of order m > 1 at x = a. Then we can write P as P(x) = (x - a)^m * Q(x) where Q is a polynomial of degree k - m with Q(a) ≠ 0. a) Show that Q is a polynomial of degree k - 1 with a root of multiplicity m - 1 at x = a. c) Now consider the ODE P(D)y = e^at * B. By the exponential response formula, we know that for any r ∈ C, we have P(D)e^(rt) = P(r)e^(rt) By differentiating both sides with respect to r and evaluating at r = a, show that e^at * t * e^(at)... * (t - (m - 1)e^(at)) solves the homogeneous equation P(D)y = 0, and that P(D)(e^at * t * e^(at)... * (t - (m - 1)e^(at))) = e^at. d) There is no particular reason to stop differentiating after m times. Consider the example P(x) = -1 - 2x^2, which has a repeated root of order 2 at x = 1. Compute that P(D)(e^tx) = 6e^t - te^t. This can be done either directly or by applying the same reasoning from the previous problem (e.g. by plugging in e^rt and differentiating the result three times as a function of r). Using this, find a solution of P(D)y = te^t. Note that this is (strictly speaking) not covered by ERF or generalized ERF. e) (+1 bonus) Describe how this observation can be generalized to solve the ODE P(D)y = te^at for P(D) a polynomial. Credit will be given for completing this under the simplifying assumption that P(0) ≠ 0.
