If you were told that a ball had a wavelength of 5 x 10-26 nm at a velocity of 60 mph, what would be the mass of that ball in pounds?

Answer 1

wavelength = h/mv
wavelength = 5E-26. Convert to m.
Convert 60 mph to m/s
Substitute and solve for mass in grams and convert to pounds.Post your work if you get stuck.

Answer 2

how do I convert 5E-26 to Meters
60mph is 26.8224m/s

I am having trouble in how to write it out
(9.109E-31kg)(26.8223)
or am I dividing the 5E-26 from the 26.8224?
