Arectified triangular wave form is defined by the periodic function f(t) f(t + t) where a rectified triangular for 0 < t < fortt. 10 f(t) t - m a. find the fouricr scrics cxpansion of f(t) b. if f(t) represents the driving force on a lightly damped spring system, write down (without solving from first principles): (1.) the complementary solution, and (2,) the particular solution for the mass's position.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
