In certain physical models, the nonhomogeneous term, or forcing term, g(t) in the equation ay" + by' + cy = g(t) may not be continuous, but have a jump discontinuity. If this occurs, a reasonable solution can still be
obtained using the following procedure. Consider the following initial value problem.
240 if 0sts7T/6
y" + 4y' + 40y = g(t); y(0) = 0, y'(0) = 0, where g(t) = .
if t> 7x/6
Complete parts (a) through (c) below.
(a) Find a solution to the initial value problem for 0 sts 71/6.
The solution for 0sts 7n/6 is y(t) = - 6 e -21

(b) Find a general solution for t> 71/6.
The general solution for t> 7x/6 is y(t) = C, e-2 cos 6t + C, e -2t sin 6t
(Type an equation. Do not use d. D. e, E, i, or I as arbitrary constants since these letters already have defined meanings.)
(c) Now choose the constants in the general solution from part (b) so that the solution from part (a) and the solution from part (b) agree, together with their first…

- Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. A particle moves along the x-axis with an initial velocity of 30.55 fps (NOTE: fps means ft/s or feet per second, NOT “frame” per second) at the origin. For the first 5 seconds, it has no acceleration, and afterwards it is acted on by an opposing force which gives it a decreasing velocity until the particle stops at t = 10 s. a. Draw the a–t and s–t graphs for the motion. b. Calculate the velocity of the particle at t = 8 sc. Find the distance traveled by the particle at t = 10 s.
