How do we calculate the "range" of the measurements?

a) subtract the smallest value from the largest value
b)subtract the largest value from the smallest value
c)add up all the measurements
d)add up all the measurements and divide by the number of measurements

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
