Question

The mass of a golf ball is 45.9 g . if it leaves the tee with a speed of 66.0 m/s , what is its corresponding wavelength? express your answer with the appropriate units. hints

Answer 1

Solution for the problem:

w = h / p 

Where:

Wavelength = w 
h = Planck's constant = 6.626e-34J*s 
p = momentum = m * v 

m = mass = 45.9g (1kg / 1000g) = .0459 kg 

v = velocity = 66m/s 
p = m * v = .0459 kg * 66m/s = 3.0294 N *s 
w = h / p = (6.626e-34J*s) / 3.0294 N *s = 2.76e-34 m
