A spring with force constant k=100 N/m is fixed vertically to the floor. An object with mass=0.2kg is dropped directly onto the spring from a height of 0.3m above the tip of the spring. What is the maximum compression of the spring before the mass comes to a stop? What is the compression of the spring when the mass is traveling at its maximum speed?

Which of the following would not be taken into consideration when describing the quality of a sound

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
