Show your work: A wolf is chasing an elk. The wolf has a mass of 100 kg and is running with a velocity of 16 m/s to the right. What is the wolf's momentum?
The elk has a mass of 180 kg. What does the elk's speed have to be for it to have the same momentum
as the
wolf?

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?
