Suppose you are using a hand generator connected to a light bulb to light the lightbulb. Assume you use 600J of KE turn the crank. During the energy flow process, KE from your hand is transformed to electrical energy (which is only 20.0% efficient), the electric energy is then transmitted though the wires (which is 98% efficient), then the electrical energy is transformed to light energy (which is 8% efficient). How much energy is dissipated

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?
