At the indianapolis 500, you can measure the speed of cars just by listening to the difference in pitch of the engine noise between approaching and receding cars. suppose the sound of a certain car drops by a factor of 2.40 as it goes by on the straightaway. how fast is it going? (take the speed of sound to be 343 m/s.)

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^β2m on an edge at the ocean's surface, decrease by 7.5 x 10β10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^β2, delta v=7.5x10^β10. at some point l needs to be cubed. why p is divided by delta v?

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 ( Ο t β Ξ± ) where Ξ± 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 Ο ? what is the phase shift?
