When a child fires an air gun that discharges a 0.35 g steel pellet at a velocity of 162 km/h, what is the wavelength in meters of the pellet?

Explanation:

The De Broglie's wavelength of an object is given by:

where

h is the Planck constant

m is the mass of the object

v is the speed of the object

In this problem, we have:

is the mass of the pellet

is the speed of the pellet

Substituting into the equation, we find the wavelength of the pellet:

time (seconds)

answer: 0 meters/second^2

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
