An empty beaker has a mass of 750 g Salt is added to the beaker until it has a total mass of 108.06 g Using the correct number of significant figures what is the mass of the salt?
A)0338
B)3319
C)33.089
D)33 0609

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?
