How is Earth's surface most likely to change in a cold place that experiences rainfall?

Soil will loosen due to extensive network of tunnels.
Rocks will break due to repeated abrasion and stress.
Mounds of sand will form due to deposition of sediments.
Cracks will appear in rocks due to freezing and thawing.

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?
