A shock absorber is designed to quickly damp out the oscillations that a car would otherwise make because it is suspended on springs. A) Find the period of oscillation of a 1590-kg car that is suspended by springs that make an effective force constant of 6×10^4 N/m. B) Find the damping constant b that will reduce the amplitude of oscillations of this car by a factor of 3.00 within a time equal to half the period of oscillation.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

Which of the following is an example of motion in two dimensions?

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)
