Calculate the de Broglie wavelength for each of the following.
a. An electron with a velocity 10% of the speed of light
b. A tennis ball (55g) served at 35m/s (-80 mi/h)
A particle has a velocity that is 90% of the speed of light. If the wavelength of the particle is 1.5x10 to the power of -15m, calculate the mass of the particle

Use
Planck's constant = wavelength x momentum
and momentum = mass x velocity
and plug in the numbers.
