Astring of length l = 0.850 m stretched between two points is subjected to a tension t. when the string is plucked at one end, it takes 2.25 ms for the resulting wave to move from one end of the string to the other. if the mass per unit length of the string is 4.60 ✕ 10−3 kg/m, what is the tension in this string?

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?
