Question

A car with a mass of 1250kg is traveling at a speed of 15 m/s before it stops in 3 seconds what is the change in momentum of the car?

Answer 1

wavelength equals speed of light / frquency of oscillation....luckily this is the easiest way to do it if you know calculus, so we do not know frequency but we do know the change in state level which is amplitude. and there is a equation relating frequency and amplitude. frequency times wavelength equals amplitude. so if we rearrange we get frequency equals amplitude divided by wavelength...however we dont know wavelength but we do know the speed of light and plancks constant.. plancks constant is 6.62 x 10 ^-34 the equation to relate the planck and wavelength is wavelegth equals plancks constant divided by speed of light which is 3.00x 10 ^-8 . Use these equatuions to find wavelength Message me back right away so I know you're doing the problem well or if you need any more help... BTW SORRY FOR MISSPELLING TOO LAZY TO CORRECT THEM
