Aspring has a constant k= 10.32 n/m and is hung vertically. a 0.400kg mass is suspended from the spring. what is the displacement of the end of the spring due to the weight of the .400kg mass?

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?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

What is the increase in density of a medium due to wave travel?
