1B. 21

Postby Jenna Ortiguerra 4G » Fri Oct 11, 2019 11:39 pm

1B. 21 I am having trouble with how to approach this problem. A baseball must weigh between 5.00 and 5.25 ounces (1 ounce = 28.3 g). What is the wavelength of a 5.15-ounce base ball thrown at 92 mph?

try converting all of your given values into units that you need for each part of the De Broglie EQ:
convert 5.15 oz into kg
convert 92 mph into m/s

from there, you should be able to multiply the mass of the baseball times the velocity and get the momentum
then plug it into wavelength = h/P

You should use the equation, wavelength = (plank's constant)/(mass x velocity). You can convert the mass of the baseball into grams and then just plug in the rest of the information.
