A 40 kg bear cub is floating on a log in the middle of a lake. It leaps horizontally from the 600 kg log. If the cub’s speed at the moment she left the log was 4.0 m/s determine the speed of the log.

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?
