No calculators or extra sheets of paper are necessary or allowed. Credit will only be given for answers written in the spaces provided. Be sure to give the units where appropriate. A driver suddenly applies the brakes in a car moving along dry pavement. Assume A, B, and C describe the constitutive law of a capacitor, and the x-axis represents voltage.
C describe the constitutive law of a damper, and the x-axis represents velocity.
If x1 and x2 are both moving with simple sinusoidal motion at a fixed frequency, then they will continue to move with simple sinusoidal motion at the same frequency. If the current motion is a linear combination of the two normal modes, then the motion will continue in the same linear combination. Answer each of the following questions with a number. A statement is false if it is not always true. Put an X by the best answer.
